I have checked the following questions:
What to do with abandoned questions?
How should we define "Abandoned" as a close reason?
Changes to how we close abandoned questions
Closing abandoned questions is harder than it should be.
And I have not seen an answer to a particular doubt I have about the time.
For example, what should constitute an abandoned question. For me it should be a question that is not affected by the current Ubuntu release. For example, if the question is in regard to a problem in the Ubuntu 11.10 version, then, until a new release appears, the "countdown" for the abandoned status should not start.
After a new release is made, typically most people update to the latest. This increase might help solve some of this question if by chance somebody sees it and finds that it was fixed on the new release. If this is not the case, the OP should check in a time period of at least half the release cycle (3 months) to see if the new Ubuntu release fixes the problem. If not, he or she should update the tag to reflect that it was tested on a new release and it is still a current problem.
This way, moderators and helpers know that if a question is on the current Ubuntu version of is at least 9 months old with no changes, then it can be thought to be an abandoned question. There are several users that might still be waiting after 5 months for example for a solution to a question and not find it until a new releases comes out. If they do, then good, question is answered. If not they can update the tag to reflect the new version. If they don't flag it or test the new version, then it is most likely a forgotten question that will surely be abandoned.
But the point is that a time frame could be added to abandoned question so that at least 6 months need to pass to start giving the question a doubtful eye. If the 9 month period arrives then that question is pregnant with an abandoned flag.
Sorry for the english, If something was written wrong or confuses let me know. Just wanted to clear the time frame about abandoned questions.
