Is it possible to have more granularity in of time-span for locking questions? Currently the available choices are 1 hr, 1 day, 1 week, and permanent. There are times where longer, but not permanent locks would be desirable (1, 2, 3 months for example).
If we were to implement something like what D. Savitt suggested in regards to contest questions, one possible hitch is that contests such as the USAMTS or the MathCamp qualifying often take longer than 1 week. Under the current system the only choices are either to come back every week and re-lock it with a 1 week lock, or lock it permanently and re-open after the contest expires. Both requires moderators to remember (or be reminded) about the locked question. And as we know well, moderators are only human and can be fallible.
The ability to lock a question for a customised length of time, or just the ability to lock questions for "X number of months".
