Some here have suggested that the license terms are unpalatable, so I suggest you look that page up and see for yourself if you can live with it.
I have about 250 members on my forum and not one complained when I switched from phpbb. That's got to say something.
It gets my recommendation anyway
It's feature rich, is SEO friendly, has a great admin section, a great banning/post moderation feature, is quick, fully customisable and the support via Lewis Media and their support forums is great.
Edit: We switched from PHPB too and no-one complained about the forum itself, just a few complaints about the choice of skin/theme we adopted (custom designed), user wise, they all loved it.
There are many different 'designs' of it as well that includes a sidebard should you want to put ads down the side and such, or you can near enough rewrite the entire code if you know what you're doing. It meets W3C standards and can even be accessed via mobile technology. The best feature? Comes with a spell checker :)
