Recently I've been seeing some questions where the user wants people to check their solution or proof, and there's usually one comment that says "that's correct" and nothing else (no answers, etc). For example:
- How many six-letter strings constructed from the English alphabet contain at least one of the vowels $\{a,e,i,o,u\}$?
- Proof-verification: Show that there exists an exact sequence

Question about the proper interpratation of integral notation
Is it possible that we add some kind of "check mark" like button that the user can press if they feel that the question has already been addressed and solved (perhaps not attributing rep points at all) even if there are no answers? I'm not saying that comments should be counted as answers, I'm just asking if it's possible to have some kind of indication that a question has been addressed. In the case of writing my own answer to these questions, of course I understand if there's been a long comment thread with people talking and they get an answer that way. But the cases in which people just post one wikipedia link, or a "that's right", it just seems rather a waste of time to write an answer for a question that's already been addressed completely.
But whatevs, it seems people are against it, so I'll let this question die.
Edit: I don’t quite understand the downvotes—I’ve looked at the other questions and it doesn’t seem like they address this particular issue. Furthermore, I think this commenting problem is still an issue, a problem that hasn’t been fixed regardless of how many questions have been asked about it. The “community wiki” solution is not very practical—I mean who wants to transcribe a whole bunch of two-word comments or comments containing a Wikipedia link as an answer? And if they aren’t getting deleted (and it seems they are not), won’t they just clutter up the site, edging out questions that actually haven't been addressed?
Certainly it is possible to post an alternative solution or whatever, but I think most cases where this happens are trivial enough that there is not much room for extension, and can simply be considered “addressed” when there is already a comment answer.
