Sometimes I see questions asked by super-low-rep users, even reputation-1, which have one (or more) reasonable answers with some upvotes - but no answer is accepted, and the OP doesn't make any comments or indicate they have reason not to accept; they just disappear, possibly forever.

What should I/we do in these cases, as a non-moderator, non-answer-provider, but relatively high-reputation user?

**Note:** I mean what should I do _now_, not what possible solutions could there be to this issue involving changes to the system etc.
