I tried that but I keep getting errors when trying to import and keep the topic numbers the same. It gives me something about duplicate entry error.You could do it via phpMyAdmin, removed ~ 900 accounts and ~ 3000 threads in a few seconds from the tables without running a query.
If you use that import option (to preserve source ids) then it must be a brand new installation with no content or you will get duplicate key errors.I tried that but I keep getting errors when trying to import and keep the topic numbers the same. It gives me something about duplicate entry error.
I think he meant admin as original admin account. And this would be a very handy feature if you want to keep all your usergroups permissions and template edits and whatnot.If I were in your situation, I'd start from scratch with a fresh install. No need to preserve accounts of any Admins who let the forum get to that state anyway, right?
It has been done:I remember Brogan posted a command to delete all content (for the import option Jake mentioned)
