After looking at other wikis, I think FW should develop what people want and make it simple. An often-asked request is that it includes a membership system. The answer is usually that you can do it if you have access to the server and you change the rights. While this is fine for techies we're finding many people who want to deploy these wikis are not techies. So therefore I think providing all the usability from the front-end so no one has to go to the server to make the wiki do what they want.
From an admin panel, users can be given the following rights:
1. A master admin
3. Regular members.
The admin panel is only accessible to master administrator and the other admins can be given access on a single-user bases.
When people register they make changes and their username is associated with their changes.
