Sean, now I remember. The comments settings and CM Answers Pro interact a little bit. I’ve turned the comment ticker off, but now the Q&A doesn’t show beneath a blog post. I can live with that for now, at least.
Also, I love what BuddyPress does, but it really attracts a LOT of forum spammers. I use the Stop Spammers Spam Control plugin to block domains, and it works beautifully!
