I just click Improve edit, edit it to be what I want it to be and then leave the following canned comment:
@WhoeverMadeTheEdit Welcome to Ask Ubuntu! **;-)** Could you please review my [edits]() and also review the [editing help](/editing-help) to improve the readability of your questions/answers/edits in the future... **;-)**
then I copy-paste the link of the revisions of the Q, A or E in between the ().
That way you kill 3 birds with one stone:
- It's now a perfect Edit / Question / Answer. ;-)
- You educate the editors / OPs by leading by example on stuff they might not
be aware of... :-) - The user still gets his +2 rep (important for beginning users)
P.S. If I meet the same user more than 3 times and have given them three examples already, I just Reject and will give another user a chance to edit same...
