Populate a subforum with each username as a threadtitle
 

I'm making a subforum where the only threads will be a thread for each user in the system (username as the threadtitle) and then other users can provide feedback for each user view thread replies.

What would be the best way to automatically populate a subforum with 3,000 threads (3,000 users) in this manner?

Create a script to do it? :D I'm not sure what kind of answer you want here...

I'd do this with SQL, I think it's the most efficient way.

You should use the data manager and do it in batches, otherwise you may get timeouts. You should not use pure SQL to do this, as there are more things to do when adding a thread than you think.

I'm no scripter but where could I get started in learning how to write a script to do this? :o

Have a look in the Articles section and also at the Appendix in the vBulletin Manual.
