So far my test WordPress MU site gets nothing but Spam. I can tell if it is spam before the blog gets very far, but the registration is a klugey process. I want to have users fill out all their information and some extra data. I then want to see a list of these with the ability to accept or reject a blog. I also want to be able to send a personalized rejection letter explaining why their blog was rejects.
I have started the plugin and I’ll announce here when it is installed in case anyone wants to see how it works.
