They were removed, but thanks to trillian on Windows, I got them back, because Trillian can automaticaly add everyone who has added you to thier contact lists, onto your contact lists.
I'll make it clear. If they have added you, Trillian puts them on your list.
I never add people. I always get added by others. So I got my contact list back to normal.
I used to use Trillian, but it dosen't handle large amount of contacts all that well (MSN Messenger puts all your online contacts at the top of your list. Trillian dosen't. When you have over 70 contacts, it's hard to tell which are online). So I use MSN messenger on Windows and on Mac.
Remember, a Windows computer is safe if you are smart when you browse (see my sig).
