Administrators are normal contributors with access to certain tools. These tools include:
- Deleting/undeleting pages
- Blocking accounts from editing
- Protecting pages from editing
A full list is at Special:ListGroupRights.
If you need help with any of these actions, feel free to contact an active administrator by leaving them a message on their talk page or by sending them an email. Some active administrators are Kotra, Mark, and Dave. A full list of administrators is at Special:ListUsers/sysop.
