I am a web guy, so I have been tossing around the idea of starting a forum, much like the one on this site, but a completely different topic.

I have heard and read quite a bit about different options for forums over the years, but I wanted to ask your opinions. Which forum tool is best and why?

I suppose the most popular, it seems, is PHPBB. This tool seems very convoluted and difficult to use (seriously, it took me about 15 minutes to find the "search" feature).

What other tools are there out there, and what are the pros and cons of each?
