The Admin Noticeboard Edit
There are a number of issues that can only be solved by an Administrator. The Admin Noticeboard is a means by which users can contact Administrators in order to identify a problem that needs Administrative attention. Although editors are welcome to directly contact particular Administrators, posting on this page instead may be an easier way to let the entire Administrative group know of the issue (which may be particularly helpful since it increases the odds that at least one Administrator will see, and thus be able to respond to, the issue promptly).
There are only a limited number of things for which this page should be used. Many problems can be solved without Administrative intervention, and, thus, this page should be restricted to those issues that actually require an Administrator. Those are: blocking vandals, (un)deleting pages, (un)protecting pages, and mediation (only if the situation demands it).
Even in cases of vandalism, posting on this page needn't be the first step (and indeed should not be the first step). If you see vandalism, just go ahead and revert it, anyone has the power to do so. If it's a new article with no safe version to revert back to, tag it for deletion. In both cases you should leave a message in the talk page of that user to make him/her aware of why that kind of edit is unacceptable on this wiki. Only post here if that user persists in his/her actions, ignoring the warnings or if the content requires immediate Administrative attention (e.g. if the material on the page is so offensive as to require immediate deletion).
(Be careful in case that user repeatedly insists on vandalizing, avoid a revert war; it's far better to temporarily leave the vandalized version of the page up until an admin has a chance to intervene.)
To create a new request: add an item to the bottom of the list below, providing a brief, neutral summary of the issue. As a sign of courtesy, also leave a message on the talk page of any other involved users so they are aware of this discussion. If you are alerting an admin of a vandal, use the Template:IP template, with the first parameter being the vandal's IP or username.
