This was a problem in my earlier days on DarkMatters. There's no obvious link from DarkMatters to SacredWiki.
Just imagine for a second you're new to the community, you're aware there's a wiki maybe, but how do you get to SacredWiki.org from Darkmatters.org? Gogo's signature is the only place I know of with a (tiny) link straight to that address. You could visit the SacredWiki forum section, but even then, you must browse through threads and hunt for individual posts that might have links to the Wiki. There's not even a "main" thread/post with a link to it.
It seems like the kinda thing that should have at least one big proud "can't miss" button somewhere on Darkmatters.
