With my users, I would not want them in the site map because the majority of them would not understand the interface and are likely to do more harm than good. I would rather wait for an admin portlet interface to allow them to make those choices.
In reference to Nima's second paragraph, I guess I don't understand the "dotlrn admin" role enough to that it fits what Nima describes: "a sitewide admin at the IT department could take care of server maintenance while dotlrn admins are responsible for their dotlrn instance." Yes, that would be great, but i didn't understand the description in that way. Plus, the site wide admin, at least as i play the role here, does not do the server maintenance. The site wide admin creates the subject, communities and classes, users, etc. So, would the new dotlrn-admin do all that with these changes?
