Each site has a variety of closing reasons, the standards being Exact Duplicate, Subjective & Arguemntative, Blatantly Offensive, and Spam. It takes 5 close votes to close a topic. Only those with over 3,000 rep can vote to close. If a moderator votes to close, it closes automatically. It takes 5 votes to reopen a question. You may not vote twice (only once for close and once for reopen).
