At this point, I'd wait for Anton or Scott to wake up to give you the definitive answer on how the community user is meant to behave and whether or not there's something else going on behind the scenes that us mere mortals can't see.
]]>If none of the answers deserves a vote, or if there are no answers, then you could provide one. In particular, if it has been answered in the comments then that can be transferred to an answer. Custom dictates that such an answer should be community wiki. You would then have to hope that someone else voted for the answer (you could even write that in the answer: "I'm writing this answer to stop it getting bumped to the front page, I need someone to vote for it for my nefarious plot to succeed"). This is what you say in your last paragraph with the addition of the "community wiki" feature.
Of course, this presupposes that the question shouldn't have been closed for a genuine reason (wrong level for the site or some such) in which case vote to close (and/or bring it to the attention of the +3000 users by commenting on it here on meta).
Indeed, some people only answer in comments (something that I consider a bit unhelpful to the community) and I see no problem with copying the answer into a (suitably attributed and community wiki) answer for the questioner to accept.
