Every wiki in Fandom is overseen by their own administrations, and that includes the Happy Death Day Wiki. The administration consists of four types of users, sorted in descending order from left to right:
Bureaucrats have access to privileges from the administrator, discussions moderator, content moderator, and rollback groups.
Only bureaucrats have the ability to manipulate user rights, as well as block and unblock users, so this right is generally used in addition to the administrator group.
They have the ability to promote and revoke rollback, content moderator, and administrator rights as well as appointing new bureaucrats.
Administrators (also known as "admins" or "sysops (short for system-operators)") are trusted users who are generally chosen by the community and also have access to the following rights:
All privileges from the discussions moderator and content moderator groups.
Block users who are vandalizing the wiki from editing and other actions.
Grant and revoke both the Chat Moderator and Discussion Moderator rights.
Edit the community's skin and format.
Edit white-listed MediaWiki pages.
Content moderators are users who have additional tools available to moderate specific parts of the community. These tools are:
Deleting and moving protected pages
Deleting and moving files
Undeleting pages and files
Protecting and unprotecting pages
Anyone can revert vandalism and bad-faith edits, but it takes a couple of clicks in the page history to get it done. The "rollback" permission allows a user to undo bad edits with one click: by using the rollback link on diff pages, the user's contributions page, or the list of recent changes. The edit summary for a rollback edit is (Reverted edits by X (talk) to last version by Y).
Content moderators and admins have this permission by default. It can also be granted to other users by adding them to the rollback group.
These users log on frequently to edit and browse the wiki, and, hence, are the best ones to contact.
These users do not log on all the time, though are still relatively frequent.
These users are currently away (such as on vacation, etc.), but will return shortly. It's unlikely they will edit or respond to messages, except for rare occasions.
For whatever reason, these users aren't able to log on to the wiki for an extended period of time. Their inactivity has been excused due to unfortunate circumstances.
Unfortunately, these users have stepped back from their roles on the wiki. They will retain their privileges so long as they desire, and are welcome to resume involvement in the future if they so choose.
These users have left the wiki for an unknown reason without communicating a reason for deserting.
