as far as my knowledge of mIRC goes, you select an "IRC network" from the drop-down box and then select a server from the drop down menu below the last one. Fill in the name fields, then hit the "Connect to IRC server" button and wait till its done its thing.

then to join a room you type "/join #roomname" in the box at the bottom. and then you'll join that room, or create it if it doesn't actually exist.

But i guess you actually want a list of places to go... which i can't help with. I've only been on Quakenet and another PC games centred one, for clan related thingies. Once you figure out a room to enter, put it in the "perform" list so you'll automatically join that room when you connect.

PS. I never fiddled around with Port settings, i've left them as they are and they just work.

Edit: the "#help" room may be a good idea... read the MOTD for your network if it has one...
