Message board - Individual message board
This page shows several options for an individual message board.
Each message board will show a list of the 20 most recent message threads posted to that board (if there have been that many) Each message will have a small check-box next to it; clicking that check-box, and then clicking the Delete selected messages button will delete those messages from the message board.
If there are multiple replies to a single message, keep in mind that each will need to be selected individually; deleting the top-most message in a discussion will only delete that message, not all of the replies to it.
From this page, you can also click the Message Board Setup link, to go to the Message Board Details page (https://www.iclub.com/faq/Home/Article?id=227), and change any of the settings specific to the message board.
