There's a list of Common Lisp resources on Xach's blog [1] that includes communities, which remains relevant despite being an old post.

Also, contacting one of the people associated with a blog listed on Planet Lisp [2] would ensure that it appears there and might be seen by a wide yet relevant audience.
