tc.umn.edu, gold.tc.umn.edu, or maroon.tc.umn.edu are all valid for
email addresses at the U. In future, you won't see gold or maroon anymore
because they all will be converted to just .......@tc.umn.edu. However,
the change won't be made at least this quarter. That's what I heard from
one of my classes regarding offical email address issue. :-))
