We're using Moodle 1.9.3.
I wound like to know where I can find out when a user's role was overwritten?
For example I gave a user the role of a course creator in a category at the 01-Jan-2009 and when did someone removed the role assignment for that particular user?
In the logfiles I cann't especially look for role overwrites, in mdl_roles_assignment there is a timestamp.
Can anyone help?
