There had been a spate of spam comments on c.p.o lately. As a temporary measure, I've turn off automatic comment approval, but that leaves me having to approve comments for long-time users, and slows down the experience for all of you.
So, improved strategy. A new role, "verified user", is now allowed to post comments without approval. You can become a verified user by choosing the "My account" link and the "apply for role table". I'll verify anyone who I can reasonably assure myself is an actual MUSHer and has been around the site for a while.
