Twitt'd 
Posted on July 29, 2008
Twit' using your favorite instant messenger
Just add Twitt’d to your favorite IM’s buddy list and say “hi”.. or “what’s up?” or.. whatever. You will be asked for your Twitter username and password (sssh! we’ll keep it in secret!)
Twitt’d will send you updates from people you are following and everything you send to Twitt’d will be posted to your Twitter timeline!
There are a couple of commands, too (just type them in, including slash, and hit enter):
/updates – toggles update receiving from people you follow
/changepassword NEWPASSWORDHERE – use this if you’ve changed your Twitter account password
/forgetme – delete your Twitt’d account
