I figured there was one out there somewhere. This one is new and not all that active, but worth checking out (and making more active)
You can post your self-pubbed book there, with blurb and cover shot for free, hey! and check out the forum.
Moderated by at least one guy (flashgordon over there) who knows his onions about publishing and is a resource in himself.
Something like this, at this stage, is sensitive to misuse, so don't clutter it up if you aren't serious about self-publishing.
