Integrate X7chat

[TehCraw]

Okay, so I added the chat room button to my menu bar, and added a new page to my site with Simple Portal. The I put the chat page in an <iframe> and stucj in the page. That all works fine and dandy, but here's my problem...

How do I pass people's usernames to the chat software so that they don't have to register a separate account for chatting?
