Buy vBulletin. I personally prefer it. The more I see of these other boards, the less I feel they offer than vb, other than "hey, I'm free and kinda like VB!"

Check the "Options" at the top left, or scroll to the bottom, and view the templating structure. v3 should be arriving soon.
At any rate, the name dotForum.com is nice. It would be a nice twist to have the domain registered in all major TLD extensions. NameForums.com is also a nice name, but I'm not sure how busy that forum is... the "name" is only part of the equation.
If I wanted to start a forum like this one, I would personally pay up to $100-$125 for that name, along with its dotForum(s).com counterpart.
The problem with forums is that one needs to BUILD the community actively. Posting alluding to it in another forum, never usually leads to anyone really wanting to come over and stick around, --or get a buzz created. So, starting any forum is basically adopting a challenge... one that clearly may not pay-off in the long run.
Critical Mass is extremely important and not simple to achieve. I've run a messageboard for years, and it's never achieved what I would term "critical mass". DNF has however. It can however be lost, but not easily.
Best way however to gain visitors is providing an "out" (that other members support) when another forum shuts down. But, it really does NEED to be dead, or about to die, permanently and for a longtime (like Afternic's).
