AIM is preferred. But all the other losers use MSN, so its hard to avoid

I actually spent some time learning how to hack AIM to let me use font color settings that aren't in its default settings. Web hexcodes for colors instead of the .... 15? or so defaults that they limit you to. Also I learned how to make my own expressions. So by far AIM is the prettiest most customizable chat program for me. Although I use an ancient version 'cause AIM 6+ was just an ugly abomination regardless and it just kept getting worse so I have my doubts the newer versions are any better

AIM lets you pause and/or resume downloads, so when a transfer fails its not a complete waste of time

All-in-all I really don't know how it is that it's not -everyone-'s preferred chat client. But maybe versions 6+ can be blamed for that xD
