Hey there, up until recently I had Microsoft messenger for mac, plus a bunch of people who I wasn't chatting with because they were on different clients I hadn't gotten around to downloading on my mac, so now I want to do some housekeeping. Especially since I strongly suspect Microsoft Messenger is an evil app that made my computer CPU run too much, and is also under investigation for getting a Win machine in the house so tangled up it brought down the wifi for everyone (one more instance where I was thanking the gods of tech for the iphone, since I could still get online). Anyway this time I want to do things right and get a GREAT app I want it to talk to as many clients as possible, and be light 'n airy so that I can have it on working in the background all the time if possible (macbook is the 2.2GHz 120GB model from about 2 years ago). Money-wise, obviously free is nice, but most of all I want to do this right, so I don't object to paying a bit. It also doesn't need to be fancy and allow sound/video messaging, although transmitting files is really handy when you want to show a person a picture nice and quick - be handy to have that. I really wanted to add a poll, but I don't know what the options could be So, give me all your favorites! Then I'll see if I can add a poll at a later date )dunno if that's possible).
