We seem to get a lot of questions asking something like "my site is broken, please help" with very little explanation. There are also a lot of questions where the answer is "read this page of documentation".
I think it would be useful to have a clearer notice when users are asking questions, saying a few things:
You must include your site's URL if possible so we can see where the problem occurs.
Please check if a question has been already been asked.
There is a demo (including admin access) if you just want to try Q2A.
There is lots of information in the documentation on how to implement single sign-on, plugins, etc.
This should be on the question form somewhere, not stuck off to the right in the sidebar (I don't think people read that).
