Three ways to help revive a question are by:
- adding upvotes to it
- editing to improve it i.e. provide additional details or clarify existing details
- offering a bounty
In the case of the question you linked to I offered a bounty of 50 points (the minimum) and within an hour or so the question now has an answer. Whether or not that answer is ever accepted (which can only be done by the asker of the question) is not as important as whether it starts to accumulate upvotes to indicate its quality.
As someone with low reputation (6) at the moment, only suggesting edits from the above is open to you, so I hope the value of earning reputation has become apparent. Once 50 rep points no longer seems a lot to give away, it makes drawing attention to questions you want answered easy to do.
