Hey all,

I'm interested in getting an independent opinion if you've used both phpBB and vBulletin.

I'm starting to set up a site with a forum and would like for the forum to be:
- in php
- have seo friendly urls (like mydomain.com/forum-name/this-thread-title-here
- secure
- able to have integration with my own site's php session log-in, so people will only have ONE account
- readable/clean code, so I can extend it in ways that I want

Those are the main requirements. I'm a good php programmer and I could've programmed my own solution, but I don't want to reinvent the wheel.

I've narrowed the choices down to phpBB vs vBulletin.

vBulletin looks better but I don't know if it's easy to set up seo friendly urls. I'm familiar with htaccess and what not but:

I'd like to hear what some people think before picking a framework.
