How to add a massive post at the end of each thread?
I've closed my phpbb forum two years ago and now I'm going to open it again with Vanilla: for this reason I'd like to add at the end of each thread (there are hundreds...) a post explaining that this is the new post after the closing. A sort of boundary line.
How can I obtain this in a simple way without manually writing a post in every thread?
Can I give a command in the terminal/myPhpAdmin?
All these "advise post" are by the admin, obviously. Better if they would have the same date&time.
Thanks in advance.
