Bureaucrats
These users have the right to assign new System Operators and Responsible Users.
System operators
These users are the administrators of the site, having broad control over pages and users.
Chat moderators
These users are similar to normal users, but with additional rights to moderate the in-built chat system. If you distinguish yourself, you might be made one as a precursor to becoming a Sysop.
Responsible users
These users are similar to normal users, but with additional rights to revert pages and stop vandalism. If you distinguish yourself, you might be made one as a precursor to becoming a Sysop.
Currently, all of the responsible users on EVA Database are inactive.
Inactive staff members
These users retain their rights, but haven't been around in a while.
