I've looked at all five or so modules and settled on AOLIM because it seemed to be under fairly active development (last update was just last month)...I'll try with the others to see. Of course, I may also dig into the roll your own functionality that is shown in the perldocs but (not being a "real" programmer) I wasn't sure if I was just missing something. I have a couple of samples to go by for Net::AIM and Net::OSCAR but I haven't really looked closely into that.
wonder if the roll your own in AOLIM might allow a way to poll for buddies not in your list (although I doubt AOL would let you poll blindly).
