Is it possible to give edit module permission only to host, not to administrator. I dont want to give edit module permission to administrator user.

And one more problem is that i have set View Module permission on administrator and when i view that page it shows "Visible by Administrotors Only" how will i remove this text from my page. Kindly reply me as soon as possible.

Thanks Sebastian !!
