EDIT - okay, so it ends up at the top page in that 'forum' area, looking like an active question, but is not really.

See What can cause a question to be bumped?

is the OP likely to see it?

Possibly not. I've seen quite old questions bumped, and the OP may have moved on. They will probably get an email notification however. Still, questions here are not just for the OP, and if you can give a good answer it may help someone else in the future.
