EDITED: now almost anyone can create tags – see Where should tags be proposed?
Tags can be created by the so-called regular users, moderators and admins. If you need a tag and you don’t have the permissions to create it, just ask.
As long as this space is a test pilot, it is probably a good idea to keep defaults and keep it simple. If you want to discuss the process, please go to Where should tags be proposed?
