Woflie, thanks for this suggestion! I bought the app and installed the hook. It does what it says, it bans the member - but they can see the topic AND see that other members posting in it. I posted a test thread, blocked her, and then signed in as her, like you mentioned. She will be able to see all of us posting in there. Most of our users surf our site by using "view new content" and there my test forum appeared along with # of replies, and who replied last. That app isn't really helping, but I like your idea. I just need to figure out how not to display last post info.
I know I can restrict groups from accessing a specific forum, but I'd like to create a forum in order to organize a surprise for a hard working moderator. We want ALL members to have access to this thread, except one member. This way we can all see the thread, but she can't.
If not, can any fellow admins think of a creative way I could do this? We want all members to be able to participate and chip in to help surprise this one member. Any help is appreciated!! Thanks in advance!
