[galaxy-dev] Galaxy admin users

Hi all,   I install a local instance on a linux system. And I tried to use the admin features of Galaxy, so I add my Galaxy login ( email ) to the list in the following config setting in the Galaxy configuration file universe_wsgi.ini. # this should be a comma-separated list of valid Galaxy users admin_users = xxxx@xxxx(the email I registered)   But when I login, I did not see the "Admin" menu item on the top Galaxy menu bar. Why? Should I change anything esle?
