Here you can digest how to use Wikipedia in bite-sized morsels. The tips listed below were created for the Tip of the day project, or the Styletips project, but are listed here by title and organized by subject area for your convenience.
When asking a question at the Help desk or the Reference desk, please include all the facts needed to answer the question. For example, do not ask "who was president in 1900?" without mentioning the country you are interested in. This prevents the volunteers of those departments from having to ask follow-up questions before providing answers. Friendly reminder: the Help desk is for questions on how to use Wikipedia, while the Reference desk is for questions about anything else (real world questions).
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.
