Administrators are trusted editors, equipped with the tools to keep the wiki running smoothly. They can issue blocks to troublesome editors, revert vandalism using the rollback tool, and delete and move pages. They are authorized to use the tools at their disposal to deal with issues facing the wiki to the best of their ability.
Support administrators are users who are temporarily granted administrator rights in order to complete a certain task, assist with day-to-day administration, or take the place of other administrators who temporarily become inactive. They have the same rights as full administrators but are only temporary.
