I asked a question almost as soon as I get my account. I got a few decent answers, but I didn't get the information I wanted. The question has long since become buried by newer questions, and there's still no accepted answer. Unfortunately, because there are six answers, it probably looks to a casual observer like the question was answered and I just neglected to mark any answer as accepted.
So what's the protocol for me to try to get this question answered? I see several options:
Post the question a second time, possibly linking to the original, to get it back onto the new page. This is encouraged on sites like Reddit. However, it's probably not appropriate here, since we're encouraged to check for dupes and not submit a question that's already been asked by someone else, so this probably falls under that heading.
Wait for some kind of wiki-like talk page to be implemented, then post a plea on the talk page for input and hope that activity on the talk page bumps up the question.
Do nothing further on the Stack Overflow website. If I edit my post to say that I haven't accepted any of the current answers but are looking for more, then the question might get answered eventually by people browsing through old questions to find something they can answer.
Post the question on other sites, but link to my original question on Stack Overflow. People will either answer here, or they'll answer on the other site and I can post the accepted answer here myself. This might be considered spamming for Stack Overflow, so it might be better to do this without the link.
