I'm not sure if I really need SEO done. Since my forum is getting better and better rankings for common terms already, I see no need to do more SEO than just META tags and basic stuff like that (all of which I can do myself). PS: Just added an h1 tag, no clue why I didn't do that before.
I'll give it for free. If you have a keyword rich domain like me, you do this: Have a few signature links on forums you regularly post on. Stop worrying about your SERP and let it come naturally.
