If you mean, "How do I set up a forum?", see
tomd's advice for one that looks like ccc.co.uk, if you're not fussed about the look and want a free one, search under "free forum" provider or similar. Most free boards involve pop-ups/ads (and probably attach ad/spyware to visitors), though. Here's a link to a free board:
http://chaosuk.proboards16.com/ - there's a link to the provider at the bottom of the page. If, on the other hand, you are plugging ccc.co.uk, you might get a better response if guests could see what the forum was about!
