MAMPA is an acronym for Mod_Auth_Mysql Php Administrator. It does just that. You are probably asking "Why did you code this app?" Well, there isn't a lot of apps out there that do this. The ones that do this are frankly, just plain shit. I know mine isn't a work of art, but it functions and doesn't require a fancy browser.
THIS IS THE FIRST RELEASE!
The only thing that you can do right now is manage users and groups. Soon, there will be more features, if you need a feature just ask. I will respond to you.
Screenshots? No Screenshots.
