MicroPlanet Gravity ("Gravity")
Open Source Usenet News Reader for Windows
Gravity is a usenet news client for reading news over NNTP on Windows Operating Systems. Gravity has been a popular newsreader since 1996 when it was developed by MicroPlanet. The newer open source versions are optimized for the latest 32 and 64 bit Windows Systems including Windows 7.
Version 3.0 News
September 12, 2010
Version 3.0.4 STABLE is now available on the files download page.
Version 3.0.4 becomes the new stable release.
NOTE: Do NOT uninstall V2.9 before completing the installation of V3.0, otherwise V3.0 cannot pick up your settings and database from V2.9. Once you have finished installing V3.0 you may uninstall V2.9.
New BETA versions will be numbered 3.1.x. Note that Beta versions may have bugs or trial features. You should backup before trying new betas. The old GravityBackup.exe is incompatible with Gravity versions 2.9 onwards. In V2.9 and newer, use Tools - Database - Export and save a gdx file.
Version 3.0.x includes minor bug fixes and it also includes the first draft of a new help file in CHM format, which should be compatible with Windows Vista and Windows 7. Open Help from the Help Menu or with F1. See the release notes for a complete list of fixes and changes.
Version 2.9.x / 3.0.x can be installed for multiple users and is compatible with Windows Vista and Windows 7 file systems. You can also have multiple major versions (2.8, 2.9, 3.0) on the same machine.
Read the Gravity Installation Guide (right-click to save). This guide does not apply to Versions 2.8 and earlier.
Please report bugs, requests features, or discuss Gravity in the Gravity phpBB Forums
v2.9 changes: Vista/Win7 file system compatibility - multiple users - multiple versions - new Import/Export all data or single servers - MySpell upgraded to HunSpell - online installer - new backup by import and export commands - users can type corrected word in Spell checker - repair function in Add/Remove programs - search all headers (when saving bodies) - new function in Search to search all headers - Custom headers (like X-Faces) can now be up to 998 bytes long - ROT-13 now works only on highlighted text - new button icon thanks to Al Choy. For the complete list of changes, read the "file beta changes.txt" on the files download page.
Note: Searching all headers works in a BODY rule or score condition. When you search a body you are now searching in the entire article text including the headers. A search headers option was added to the search window. This acts similar to searching bodies.

Gravity is a full featured Windows Usenet online/offline Usenet news client with an extensive feature list including Rules, Scoring, and Filters.
Versions 2.9 and higher are compatible with modern 32 and 64-bit multi- user Windows Operating Systems (Windows XP, Vista and Windows 7). These versions write databases and settings to the user account folders so that multiple users can use Gravity and have their own settings. We recommend using the newer builds.
If you are new to Gravity, simply Download and run (or just run) the installer. Just in case you do not want a newer beta test version, remember that versions considered stable are even numbered (2.8, 3.0). We recommend using the default install directory. You can read or download (right click and save as) the Install Guide (PDF).
If you have Gravity version 2.7 and higher installed, the new versions should pick up your databases and settings. The later 2.6 version data may import (maybe not).
When you upgrade to a newer Gravity version, it is best to not uninstall your existing version so that the new version will import your settings.
Older Versions 2.7.1 through 2.8 run on the Windows XP Operating System. These builds also work with Windows Vista (32 and 64-bit) and Windows 7. Users with Administrator Accounts usually do not have problems installing in "Program Files." However, databases or any file writes are to the User Store. If you are not administrator, install in another location (not in "Program Files") to reduce problems associated with permissions or Vista's User Store Cache and User Account Control (UAC).
Very early versions (2.7), work on Windows 95 and 98 (and usually XP), but no new features or bug fixes will be done on the earlier versions compiled for Windows 95/98/NT/2K.
You can help us improve Gravity. Please report bugs and feature requests at the Gravity phpBB Forums or in the trackers at the SourceForge Project Site. You can also post to Usenet newsgroups (see below).
With Version 2.9.15 and higher, the old Microplanet Help File was (finally) updated in CHM format to include all changes since Version 2.6 (Super Gravity). The new CHM Help is keyword indexed and is searchable.
Online documentation is in progress.
Thanks to the former staff at MicroPlanet; Albert Choy, Tony Edwards, and Marwan Shaban. Credit and thanks go to Al Choy for modifying and releasing the source code and his many unselfish efforts over the years. Richard Wood deserves much credit for joining the project, compiling for newer operating systems, and adding many feature requests and improvements.

Gravity has been a popular Usenet client since 1996. Originally, Gravity was shareware, written and developed by MicroPlanet Inc. (incorporated Feb 1995). It was sold briefly to Anawave software, then re-acquired by MicroPlanet. Gravity was chosen as PC Magazine's Editor's Choice in October 1996. MicroPlanet eventually gave away Gravity free of charge.
After October 2001, Albert Choy (Al, Gravity's Godfather), co-founder of MicroPlanet, continued improvements and semi official releases know as "Super Gravity". Many of these enhancements are considered standard in the versions currently in use. Web support and downloads were provided by Tom's Gravity Pages, with some volunteers providing some additional download bandwidth. Al later stripped out propriety or licensed code for release as open source software under the BSD License in December 2003.
Richard Wood took over the code work in 2008 and began compiling the application for newer operating systems, fixing bugs, and restoring functionality. With the newer compiler, the new builds are faster and more stable than ever. Database corruption is rare.Tom B. firstname.lastname@example.org 1/01/2011 Content tweaks only
