It's not confusing at all. You just add all your SNs and you can just log in all at once with one program.
I don't really like triton although it does have a better interface but the direct connect feature is gone and i like older version better
download.com can give you an older version of AIM to. i discorrage Trillian too because it would give me the retarded errors when trying to send files to my firends that have wierd/different versions of aim. I just stick to the newest aim before triton. btw- triton takes way to much memory then i like, thats why i got rid of it. all these new programs with great border animationi are great, but still consume much more memory the you really need (example: the modern skin for Mozilla, which im stupidly using)
