I have a forum that has been running for a while now, and have a couple questions:
(also, our forum is on phpBB 2.0.21)

1. Like many others, I have problems with spam accounts registering. I disabled account activation and set it only by admin, but they still continue to register. Is there any way to stop this, or is it something that we just need to stay on top of?

2. I would like to delete a lot of user accounts (the vast majority of which are these spam accounts) but the method is extremely cumbersome. Is there a way to do this in bulk rather than entering the user name and going to their user page in admin?

3. Our forum is on phpBB 2.0.21, is it possible to get it upgraded to the latest version of phpbb, and are these other issues maybe addressed in newer versions?

thanks for any help,
Chumpy
