I've been developing a chatroom module for a client. I've had it tested by a couple of programming sites and now invite you to take a crack...

Theres no real bbcode facility yet but it should be safe against xss, csrf, injection and the such like.

registered (annoying though, what you have to go through to get to chat after registering...) will have a play later.

it's because the cms can get you to do loads more forms, but this one doesn't require any. That is until you try to chat, where it forces you to set a basic chat profile.

Interesting point, i'd not thought that fully through...

Cheers
