well, there is a default usergroup inside vB, called "moderators"

you could start by transferring the users you want to become moderator, to that group.

Then, you can assign categories or forums to them to moderate, and set their mod rights for each one. If you want the users to have modrights for ALL categories/forums, you might be better off transferring them to the "super moderators" group and then check if the 'group rights' allow them to edit/delete/move other people's topics and posts.
