Give another the ability to acces the back office

Hello, how to give another person the ability to go to the back office and only the  language settings and so.

I want make a account only for translaters, how to do that?

There is a module in the market that will allow this, you can grant access to only certain areas.  I will find the module and update this post.

Look at this module, it will allow what you want to do: http://www.boonex.com/m/multi-admin-access

as above, module works well.
