Quick question (sorry for the necromancy, I've been searching the forum to no avail)
If I delete a child board will that delete every post in it? Is there some way yo bulk- move all of the posts into the parent? or do I have to do it one at a time?
When you delete a Board that has topics/posts in it, you should get a notice that will allow you to choose which board to move them to.
If you prefer to move them manually:
First go to your Profile > Look and Layout Pref - set this to "checkboxs" - "Show quick-moderation on message index as"
Go into the child board.
At the top right put a check in the box in the header
Go to the bottom of the page
Use the left dropdown box - choose "Move Selected To"
Use the right dropdown box to choose the Board you want to move them to.
Note: if you have a LOT of topics in that Board go to Admin > Posts & Topics > Topic Settings - up the number of topics to show on the page so you can get thru it quicker
