and i don't seem to understand this:
"To do this, log out as yourself (there's a link at ÂYour WorkspaceÂ http://yourservername.com/pvt/home.tcl ) and then log in as the system user (email of "system"). Change the system user's password (the default is ÂchangemeÂ). Visit the the User Groups Admin pages at http://yourservername.com/admin/ug/ and add your personal user as a site-wide administrator."
what is a "system" email? is it email@example.com?
