I've always found that a good domain name will do you a lot of favours, firstly in terms of stickability and thirdly the overall look of your site.
From past experience, the minute someone sees ".freeforums.org" or ".myfreeforumhost" etc.. there's immediately a thought of doubt, and here's why. People are reluctant to join free forums...everyone knows that a free forum can take minutes to set up, and what's to say that the Admin is fully serious about their forum. The thing with free forums is that there is no loss to the Administrator, there is no fee for the domain name, no hosting cost and most Admins on Free hosts are happy to "not" pay to have a few ads show up on their site. Because there's no loss to them, many aren't bothered if the forum fails and will quite happily pack their bags and close down the board if things don't go quite as well as first anticipated. So, there's reason 1 to get a good domain name...to cover up the fact you're a free forum.
Secondly, having a good domain name will not only make it easier to promote your site, but it will improve stickibility. How? because it will make your forum easy to access. Ideally you want a short domain name with as few syllables as possible....for example "ps3forums.com" is going to be much easier to access than "ps3-forums-for-ever-woot.com". If people are given a short, snappy domain name they're going to be likely to remember it.
Finally, it looks professional. Enough said.

this article. It helped me a great deal when making the transition between being a regular internet noobie and a website owner.
Hope it works for you too ~smile~
