There are several top-visited posts that aren't great models for new questions:
- No room for a new \dimen
- How do I fill table cells with a background color?
- Remove ugly borders around clickable cross-references and hyperlinks
- Is it possible to change the size of an arrowhead in TikZ/PGF?
- Small Caps and Bold Face
- How do I turn off equation auto numbering
- Remove Indentation for a Single Paragraph
These all simply lack a suitable MWE, but there are perhaps other Good Ideas™ that may be missing from other questions.
Should they be edited to be good representatives of what questions are supposed to look like?
