SD, a few things on the SEO topic which I'm sure you have on your list but I'm going to repeat them anyways are the use of rel canonical tags and missing meta descriptions. I'm not sure how to handle the later on multiple pages. Might need to see how the other modern boards handle this.

I also think that trying to mod_rewrite the urls so they are shorter, maybe sans the ubbthreads.php/topics would be wise too, as a lot of attention is going into shorter semantic urls.


Won't you take me to Funkytown?
