i think the program is pretty easy to use, just go into search, enable "only users with free slots", and look up whatever you need. if you cannot find it with DC++, it probably doesn't exist. all hubs have a share size qouta, if you meet that requirement you're in, if not you get booted.
DC++ isn't for n00bs who are used to the napster p2p copycats. the instructions are crystal clear, just RTFM. if you want someone to hold your hand, good luck. if you had a specific question like:
how do i set up port forwarding to allow active tranfer over passive tranfers?
i would definately guide you. btw if you are using broadband and have not setup your ports that is probably the reason you are not able to find any files at all.....because almost everybody is behind a firewall or router.
