is there a code or plugin that would restrict access to the main sites dashboard to everyone but me(

as the super admin i dont want any other user to have access to my main sites dashboard.

i currently have a code in place that restricts access to my main sites dashboard...only problem is the that the code is set up so that user also doesnt have access to even their own dashboard meaning that cant edit their blog in any way.

i think i may have found a way around this.

could i possibly use the "quick page/ post redirect" plugin to block ALL access to the main sites dashboard?

or could i use the "user redirect" plugin?

is there a code for this?

in plain english...i want no user but me(SUPER ADMIN) to have access to the main dashboard...i want it to be a restricted area...kinda like the back of a store...customers arent allowed back there...
