I'll definitely be SEOing the forum as much as the Links SQL part of the site. I just tweaked my category.html template the other day and I'm already starting to pick up a little more traffic .

I would probably use vBulletin for the forum. What worries me a bit is the usual problem with new forums - lots of lurkers and not many posters. My target market is not tech or IT based either so there would be a bit of education and familiarisation to be done.

Pity we can't post polls here, I'd be keen to see who is interested in a business forum.
