Now that we have temporary moderators on Mythology SE, I believe they have the power to update the help text on certain help pages.
I think the most important of these is What topics can I ask about here? which describes the scope of the site. I find that page important that this is a well-written and clear description, because sometimes people will try to look through multiple forums (including StackExchange sites) quickly, trying to find the best home for their question. It is also important so that if someone asks an inapproperiate question that we decide is off-topic, he doesn't feel that it was an unfair arbitrary decision because he has broken rules he had no way to find out about.
Please suggest good description that should be on that page. Partial text that others can improve later is also welcome. Please do not discuss the help text of other help pages here, but open a new question for it.
