I've just asked a question, and someone made two comments which in fact answered my question; since the answer was in the comments, I wrote an answer and made it community wiki.
Now the commenter has deleted his comments; another person edited the answer, in fact providing another solution, not an answer to my question; and a third person provided another solution, which I promptly upvoted, because it taught me something new.
Now I'd like to provide credit to the person who in fact answered my question, and upvote the edit which provided another solution, but as a proper, alternative answer. I guess I did something weird by answering my own question and making it community wiki right away, messing the whole thing up. Thus the question I'm making in the title.
