A link to a page where it shows pre tags and indents, code tags and backticks, and that type of thing. There's already an AU question floating around about how to make answers more useful, but it might be time for one that addresses formatting.
I don't know that the proposed question belongs on AU since it's a question about AU, but either way.
Edit for clarification, I don't mean a this is how you do pre-tags/indents. I mean something like "See how much better this looks with formatting"
It's something I think should be discussed.
