In How can I install Linux Mint in a VMware Fusion VM? It fails to boot, someone solved my problem in a comment. Should I ask the poster to restate his comment in an answer so I can accept it, or is there a better way to deal with a problem solved based only on comments?
Yes, ask the commenter to make an answer from his comment so that you can upvote and accept it. If he doesn't do that in a reasonable period of time, then make the answer yourself, and self-accept it.
