Have you run across a problem that requires the attention of an Administrator?
The fastest way to catch the attention of administrators in general is to post an alert to the Administrators' noticeboard (A.N.). Administrators go there all the time to see what is up with Wikipedia; one of them will see your message and will take immediate appropriate action. Experienced editors hang out there too and sometimes will answer a question before an Admin gets to it.
Another option is to paste a {{admin help}} template (with the four curly braces) along with your question on to your Talk page and an Admin will stop by shortly.
