Those are pretty impressive numbers Jack. As far as engaging them, maybe it would help having the site information be more organized and discoverable by leveraging the landing page you made here: http://crossdreamlife.blogspot.com. Turning that into a hub of sorts. Users can go there to discover resources: top posts, most active topics, popular links from the CDL library, upcoming chats, other online resources, etc. Although, I think that page would need to be a little better organized and designed to make it more useful.
I noticed that http://crossdreamlife.com simply redirects, but you could even use that URL for the landing page, and have links to the forum and your blog, as well as Tumblr, etc.
