Ok -- I've adjusted the group membership so that you have to request
membership with approval. That should cut down on the spam. (I
apologize as I'm new to the whole Google Groups online thing, so I'm
learning). I also have removed any offensive material the spammers
left in the group.
Members can now share pages and upload files on their own once again.
(I think this is safe since I'm restricting membership only to people
who I know are "real").
Sincerely,
Nicholas
