Chat Issues/Spammers

[Romeo Hotel]

I love the chat system we have, it's a very valuable feature with regards to the site. However I have noticed we get a lot of spammers/idiots (to put it nicely!) coming on to the chat and being abusive. I therefore wonder are there any plans, or is it at all possible to have a password, linked to the forum account? which would at least in turn deter people from joining and going about their unruly buisiness?

Thanks and keep up the great work!

Rupert.
