It opens up a "chat 3" window (which is uncloseable btw) and little room to type into. Is this a public chat room? Is it private? A little unclear.

Great new site BTW!!!

I'm trying different themes now and noticed that I can see there are actually three buttons on the top right of the chat box when using the 'slate' theme. They appear to be invisible on the default theme. One button makes the chat window full screen, one adds users to the chat, and one closes the pop up window.

ah, I might have mucked up some of the CSS, I'll take a look at that later this evening

I think I fixed the chat CSS? still a little buggy but we'll sort it out
