I read this from the FAQ
QuoteWhat is an announcement board?
A board where only admins and global moderators can post. They can also be setup so that you can send announcement emails by checking 'Receive email notification when new Announcements' in Notifications.
I have one of my boards setup as an announcement board yet one of my normal members was able to reply to a post. Does this mean members are allowed to reply but not start topics? If so how can I make a board where ONLY admins can post and reply, all other members can simply view.
