irc is decent, but i claim that the best out there is direct connect. check out http://www.neo-modus.com or http://dcplusplus.sourceforge.net to get the diff versions. right now, i'd say that dc++ is a little better as per what u can get but the functions are slightly less. the hardest thing is finding a good hub, but once u do find one u like, well lets put it this way...i wont be renting any movies for a while. other thing is that to get into good hubs, yer required to share a fair amnt...and i dont mean 10 gigs...good hubs are 50+ gigs shared. interestingly enough, the current hub im in has under 700 users yet over 10x the amnt of data by space than does all of kazaa.
