I'm new to this site ~ MTF TG. Anyone know how to get into a chat room?

Down the hall, second door on the left. 

Just click on chat at the top left of the screen. If you look in the chat section here in the forums it will provide you with client configuration information if you use a client.

When I click on chat, it asks for a key that I don't have. Dena, don't understand

I get a request for a nick and a channel. If I just click on start, I can enter as a guest. #help channel will allow you to speak with a staff member. Clicking on the little symbol in the upper left once you are connected will give you the layout of the chat section.

Thanks!
