ok here are some notes on the places that "dotlrn" can be found from the user's eye. I will look in the code later on.
After the change in the proc as loticed
In the control panel of every user's portal:
int the "what others see about me" ... the link has the "dotlrn"
If you login as site wide admin in the control panel - side wide administration - users :
the site navigator on top is dotlrn > admin > users
Same come with Terms, Departments, Subjects, Classes, Communities, Portal Templates, Archived Classes / Communities and Edit Pre-approved Email Servers. In all the above the site navigator has "dotlrn".
