The best place to look for help depends on what kind of help you need:
If you're doing research and need to know where to find a particular piece of information, or just want the answer to a trivia question, try Wikipedia:Reference desk.
Ask about technical issues at Wikipedia:Village pump (technical), which is a page where folks especially knowledgeable about Wikipedia hang out. The village pump is a metaphor for a community watering hole where lots of people gather to discuss many interesting topics.
