This question already has an answer here:
This is my usual experience:
"I want to post a question but I don't know what kind of questions are within the rules on this site. And since I don't want a question that took me 10 minutes to write to be instantly flagged as off-topic, deleted or down-voted into oblivion I won't post until I know the rules."
But the rules are nowhere to be found. The short site description is often not enough and doesn't include any extra information, for example Server Fault says "Q&A for server administrators" and nowhere does it say "Don't post questions about home servers on Server Fault" etc.
With the increasing amounts of new users wouldn't it be a good idea to have the rules defined on the front page of each site like on reddit for example?
