Get this for your forum, I think it's around $130 but it's well worth the investment. It will help your page rank, allow people to submit threads to social book marking websites and so forth. Do you have a particular budget for this website, if you want PM me I may be able to help you out with some inexpensive/free solutions to promoting your site and I can give you some advice. I also have my own small political forum that I recently started and I have been learning plenty.

Um...we're already running vbseo, if you'd take a look at the footer:

Sorry, when I went to make a thread it showed up at the bottom as:

" Powered by vBulletin® Version 3.6.7

But now that I see it on the home page and other places I do see:
" Powered by vBulletin® Version 3.6.7
Copyright ©2000 - 2008, Jelsoft Enterprises Ltd.
Content Relevant URLs by vBSEO 3.0.0 ©2007, Crawlability, Inc."

Good to see that your running it though.
