I am not aware of any conflict between Mudcat and Sing Out! I am proud to be involved with both.

I really don't recall whether Sing Out! has ever mentioned Mudcat, but we do not usually write about e-communities. We write about Folk Music broadly defined, i.e., its performance, history and practice and we review more "Folk" CDs (with very knowledgeable reviewers) than anyone else.

I second Naemanson's sentiments.
