I have received an answer from Mike Ramundo about approval. He said to use a "local" area, defined as "*.edu". My questions are: 1) What will happen to posts made by non-.edu's, once they're subscribed? 2) What about posts from non.edu's that *aren't* subscribed? I also need to know how to do this...Mike gave me the header info, but I think there's more to it than just modifying the header *shrug* Thanks muchly!
