Do you have a difficult question you can't find the answer to on your own? Or, would you like to take a break from editing and perhaps share your knowledge with others who have questions? If so, then take a trip to the Wikipedia reference desk to ask or answer those tough questions.
The Wikipedia reference desk works like a library reference desk; ask a question there and Wikipedia volunteers will try to answer it. This is great if you're doing research and need to know where to find a particular piece of information, or perhaps just want the answer to a trivia question. Note: Giving out legal or medical advice is prohibited, but they can point you towards relevant articles you can check for yourself.
If you need general help with creating and editing articles on Wikipedia, try Wikipedia:Questions or ask at the Help desk. New editors might find the friendly atmosphere at the Teahouse great for getting editing advice.
