    The administrator permission has most of the same user group rights as an administrator on most other projects. Though we use a lot of common sense here and ask that all administrators and registered users do the same, prospective or new administrators are encouraged to read the official policies listed at TestWiki:Policies (especially TestWiki:Main policy). In general terms, this means undoing or otherwise reverting any tests you do and performing test blocks on either (a) User:Example (or User:Example2 and User:Example3) or (b) yourself. If you do wish to perform a test block on another user, a best practice, which you are strongly encouraged to practice here on Public Test Wiki is to obtain their consent, in writing and preferably on-wiki in advance.
