method overload in a custom role provider

Hi all

 I'm implementing a custom role provider and would like to track whoever makes changes to the roles.

In doing so for the method
public override void AddUsersToRoles(string[] userNames, string[] roleNames)
 I would like to add an additional input parameter
public void AddUsersToRoles(string[] userNames, string[] roleNames, int changer_id) Go to the complete details ...
