1. You need an IRC client. Telnet works, and there are several IRC clients to choose from, but I recommend MIRC.
2. Connect to the best Sorcerynet client for your area. Some examples are valinor.sorcery.net (6667), cookie.sorcery.net (6667), and shire.sorcery.net (6667).
3. Type "/join #ThirdJunction" once you're connected.
4. Create a character with background (history) and powers. Register the character with the clan Leader or Walker whose clan you want to join.
5. START ROLE PLAYING! Have fun!
