If someone provides a good edit to my post, what is the proper way to provide feedback or thank that person? Is it necessary? I do not yet have enough rep to edit other posts, and expect that I will be reluctant to do so other than typos and minor edits, so I expect some positive feedback on an edit would surely be welcome.
A thing you could do, related to this question is find a post of their's at 9 upvotes or something like that, and so long as you think it is a good answer, you could upvote them there. I wouldn't encourage upvoting a bad answer, but I completely understand the desire to show your appreciation.
