The Reputation Privileges state that editing should be:
- to fix grammatical or spelling mistakes
- to clarify the meaning of a post without changing it
- correct minor mistakes or add addendums / updates as the post ages
- add related resources or hyperlinks
It also says, "Try to make the post substantively better when you edit, not just change a single character. Tiny, trivial edits are discouraged."
So, can anyone tell me how I could edit someone else's question and make it better? Should I presume that I understand the question being asked better than the asker? Or would it be better to simply make a comment on the question that clarifies or asks that the question be clarified?
Also, with regard to the "Tiny, trivial" part, does that mean I should not correct spelling/grammer errors should I see them? One of the sample reasons for editing is "corrected spelling, fixed grammar", after all.
