Changing default membership option

Hello @ipstenu, how′ve you been?

I want to modify the default membership option, I′m using this plugin to my multisite network and I want to set the default membership to “Automatic” for the entire network, and I′m going to hide the Join My Multisite menu from the admin to be visible just to super-admin, so my users can not change and new sites created are set to the Automatic membership configuration automatically.

Is it possible? I mean, the changing membership part.

Thanks

Derek
