Click File->New Connection. Enter your desired user/nick name in the nickname field at the top and enter 'irc.irchighwaynet' into the Chat Server box. Check the "Remember this connection box". Click the blue down arrow to expand the preference pane. If you want to use SSL for security, change the Server Port to 9999 and check off "SSL connection". If you're ok with a regular connection, leave SSL unchecked and make sure the server port is 6667 (the default). Enter a username and Real Name into the boxes. Don't actually use your real name, as both of these fields will be visible to others on the server. Leave Server Password blank. If you want it to automatically join the SnF chat room when you connect to the server, hit the + button under Join Rooms and enter #samandfuzzy. Then click Connect. It should now start connecting to the server and the server should show up in your Connections window (hit command+1 if the Connections window isn't visible). If you want Colloquy to connect to irchighway whenever you run the app, check off the checkbox under the * column.
Registering with Nickserv (for any OS/client):You can register your nickname with Nickserv if noone else has already registered it. This prevents other people from using your name. To do this, type "/msg Nickserv register [password] [email]" except replace [password] with your desired password and [email] with a real email address you have access to. They'll email you a verification email with instruction on what to do to finalize your registration. From now on, every time you log in or change your nick you'll need to type /nickserv identify [password] to log in. Some apps, like Colloquy, will prompt you for the password when you log in and can remember it and submit it for you every time you use the nick.
EDIT:
Don't worry Knight, it's not all Pokemon nudity discussion. There's plenty of human nudity too.
