Ask intelligent questions
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).
