Don't let go of shrapnelcommunity.com, in fact hang on it it as it had what, PR 5 with google. That's very hard to come by and makes the domain itself very valuable. Using a 301 redirect will transfer all that page rank to you over the span of 3-12 months (it was a very large forum).
I don't know how you're redirecting it right now (hopefully 301 with it in a different folder). Don't point it directly here yet. Infact, you might want to throw up a mass-302 redirect (moved temporarily) so google doesn't strip you of page rank for broken links and just update it with 301 redirects as you go.
By the way, if you want to have clean URL's (which search engines goes nuts for) all you need to do is add this to your .htaccess file. (oh, hypes act as joiners to the search engine allowing stuff like "our games" to be treated as a signal phrase and not two words). By implmenting this, you won't be able to browse your site offline and you'll need to tweak image paths but it's worth it.
