The reason is because I'm making a forum software.
You don't need to do anything exactly advanced.
All you really need to do is be able to have something to check all boxes when selecting forum / usergroup permissions, once click "Quick Edit" it opens up on the same page with an editor box, etc.
Let me know if interested. (By PM).
PS. Any money made from this project, you will get at least 30% from it.
