Security feature: you can enable "Off The Record" encryption used by Adium and many other chat tools. The whole process takes less than 10 mins.
1. Go to the OTR Website www.cypherpunks.ca/otr/
2. Scroll down the page and download "installer for the plugin for gaim 2 beta 5."
3. Use Universal Extractor (http://portablefreeware.com/?id=641) to open the downloaded executable without going through the install process.
4. From the extracted folder, delete "[NSIS].nsi" and "$PLUGINSDIR" and move all other files to your GAIM install directory under \App\Gaim\plugins.
5. Open GAIM and click "Tools" in the menu bar and then "Plugins." In the Plugins window, check the box next to "Off The Record Messaging".
You're done. The plugin should then work normally to allow secure chat between you and other OTR users.
Hope someone here finds that useful.
