I want to point everybody's attention to two changes that will impact your user-experience here on Math.SE
The first you may have already noticed: the old FAQ page has been replaced by a "help center". The announcement on Meta.SO is posted here. As is mentioned, this is a work in progress. If you find that the the new help center page can be improved in anyway, please either leave an answer in the post I linked to above, or open a new feature-request or bug here on Meta.Math.SE as appropriate.
The second change will be rolled out next week: the voting to close system is going through an overhaul. Let me summarize some of the more noticeable changes here (though you should keep an eye out at the Meta.SO link above for most up-to-date information).
- Duplicates: when closing a question a duplicate, you must select a question that already has an answer. (This, however, can be overridden by moderators. So flag away when necessary!)
- Facilitated re-opening: previously we have relied on meta threads to reopen a closed question. Now, if the OP edits the post within five days of the closure, the question is automatically appended to the re-open votes queue.
- [On hold]: In conjunction with the previous point, for the first five days after closure, the question will display as [On hold] rather than [Closed]. Functionally it is the same as the previously [closed] questions (no answers can be added etc). After the five days are up, the text will show as [closed].
- Not a real question and Not constructive: these closure reasons will be removed and replaced by three spanking new ones
- unclear what you are asking
- too broad
- primarily opinion based
Off topic: you can now select one of the "standard" reasons for closing a question as off-topic, or you can enter a free-form suggestion. The list of standard reasons can be edited by moderators. (Once this change rolls out, feel free to put in suggestions below for what should be our standard "off-topic" reasons.) For more details please read this Meta.SO post.
As a side effect, it appears that ordinary users will no longer be allowed to vote to migrate questions.(See Shog9's comment below) Note that perhaps one way to address this previous meta question would be to propose a target site in the free-form field, and also flag for moderator attention.
- Too localised: is now absorbed into off-topic, so won't be present as an option anymore.
Edit (26/6/2013) The new closure mechanisms have been rolled out. It appears that we have some "standard" closure reasons built-in, including one for homework questions. Please comment below if you have suggestions for the "off-topic" reasons.
