Twitter is a pretty cool little website, so after some suggestions from the TA forums I've integrated posting to Twitter from TrueAchievements.
If you have a Twitter account you can now auto-post achievement wins to your Twitter feed when the scanners pick them up. Simply set up your account on the Customize-Twitter Settings page and let the TA scanners do the rest!
There are also a couple of new Site Leaderboards, for forum posting and solution voting.
And the Report Gamer code is finally finished, so if you did report someone for Game Saving then that will be investigated shortly.
