There are lots of comments that are short answer, generally under the guide of "I don't know for sure but here is some stuff" or "here is some advise" or "I think that" or "how about…".
You should not answer in comments. Not partial answers, not full answers. Not "leads on" an answer. Not "I would answer but I'm tired/just woke up/am drunk so I'll just say this..." Not answers that you think aren’t good enough to post as answers. Not little helpful tips, not helpful suggestions, not useful anecdotes. […] Answer in answers.
What’s the best way to communicate the situation to the commenter or the moderators so that this stuff gets posted as answers, or at least not as comments?
