Each year I set up a new board for research discussions.
I was getting tired of setting up everything, relearning once a year the whole shebang. So I decided to upload a previous backup into a new install and just delete the posts and users, to keep the structure intact (forums, groups, permissions etc etc).
(I tried 3.2 but it doesn't seem to work for me on my hypermart account, no one seems to know why it won't install)
anyway, I installed a "new" 3.x, uploaded the backup from last year, and now am seeing what needs.
