Some Questions / Teamcreation & Languages

Hello we have bought your theme and have a problem with creating a team. if a user creates a team he can change the layout with the visual composer. This is also fine but is it possible to restrict the user to delete parts of the layout?

If this is not possible, how can I create a team as admin and give the team rights to a user?

Is it possible to remove certain countries and languages for the team and user creation? There are too many that we don’t need?

thanks for the help
