You'll never go back. My sites bigger than this and i've been much more happier with it over phpbb2. Phpbb isn't search engine friendly. Vbulletin has a sitemap feature that will get your forum posts indexed by google and other search engines.

If not, then i highly suggest upgrading from 2.0.1 to 2.0.13
There are so many exploits running around the internet that 2.0.1 is an accident waiting to happen. Notice how phpbb has jumped from 2.0.10 to 2.0.13 in in about month?
Or you could be up to date and just haven't updated the footer. IDK

Techware has great reviews, but the forums aren't as impressive as they can be

That's my suggestion, yay or nay?
