I have a multisite network, where the admins of each site are able to add users to their site. My problem is that if they select the same username it will not work.
So I am thinking if it is possible to save the Username field with a prefix. Say the admin adds a user called
johndoe to a site called
mysite then the user should be saved as
Would this be possible to achieve?
I am talking about the Users->Add New User in the backend.
Hope there is a way to do this! Either with PHP or jQuery?
