User Administration Tool


 


I've started writing some code for a user administration tool. I think this might be interesting for wikka-based projects with a large number of registered users.
This action will enable Wikka administrators (or, in the future, users belonging to an Admin group) to have access to several user management functions from a single page:


The code below (to be saved as actions/useradmin.php and used as {{useradmin}} ) is just a very first draft. Contributions and improvements are welcome (especially to make the code lighter).
