Sorry, I'm not yet a mathematician.
For example, when I solved a problem but I'm not sure whether it's right, is MSE a good place to put a peer-review post for this? If so, what's the suggested behavior? Directly write the solution in the original post or write it as an answer?
As far as I've experienced, sometimes it doesn't draw much attention, then is it appropriate to start a bounty for this? I found a rough case. For example, after you start a bounty, you get an answer like this:
Yes, I think it's right.
Or just pointing out some minor mistakes, say typos. Is it deserving for a bounty? Or is it an acceptable answer? If I think it's not worthwhile, can I downvote it? The reason for the behavior of downvoting? After all, it's a response.
I want to know the etiquette for this kind of questions.
