Step 1.
Get an application.
http://www.mirc.com/get.html works best for this tutorial. It's nice, basic, small and efficient. A notice will appear to register online. Ignore that, the software will continue to work forever, even after your "evaluation period" has ended.
Step 2.
Type /server irc.animeai.com:6667. This will set your connection to the right server and port. After that, type /join #yaoiai or just /j #yaoiai to find the main chat and ask us any further questions. ^^
