I used one of my msn accounts for gaim, then when I deleted the account to add a different one, it saved all the contacts from the previous, and it's auto adding anyone from the old account that's not on the new account.. I don't know if gaim was meant to automatically do that, but faceprint on freenode #gaim said I should send a mail to this address..
I wanted to use this new msn address for different contacts (work), so this was a little bit of a hassle for both me and whoever it auto. added from the previous account..
Other than that, great work to all the developers, etc.. it's a great client!
