Can we do it Porfiry? Can we? Huh? I can't really think of anything wrong with it but if for some reason you don't want to then....I guess not. But I used to have AOL instant messenger and the Yahoo one but none of my buddies up heeya in maine did so i got rid of them, but since you already have those two there what's one more?
The makers of vBulletin didn't like MSN for some reason? Strange there isn't a field for it. If you use Trillian (yes, named after the HHGTTG character) you can be connected to MSN, Yahoo, ICQ and AIM (despite AOL's efforts against it) all through one program. Trillian does make things easier, not having to worry about downloading and then running 4 IM programs for various people.
