Welp, I still don't know much about it, but I do know that if you go to the connections and type in gnet2.ath.cx in the box that has "remove" and "add" next to it (it goes 2 thru 5 I believe and 4 works best for me) it will bring up a bunch of people, and maybe if you're lucky there'll be some people with files. Make your outgoing more than 2 (but not too many b/c then it gets NUTS) and you'll have more of a chance of having a few connections to some people. By the way, if none of the gnet2-5 works, try changing your ports in config/your connection, 8080, 80, 23,6667 and 6346 work the best, but it's not guaranteed to work for everyone (press update if you want to keep the changed port.)
Hope that helps
