SEO Optimization for Forum

[ddboards]

Ok, first off here is my site:

Domain Discussion Boards
http://www.ddboards.com/

Now that you know where it is, here is my question. I have installed Mods on there for "pretty links", have setup META tags, have some content, though the forum is still new and is growing in members slowly (always lookin for more .. ) Anyhow, what else can I be doing to help with getting my domain to show up on Google's search result under the specific keywords:

Domain Forums
Domain Reviews
Domain Appraisal
Domain Appraisal Forum

Any Suggestions?

Thanks,
