They last roughly 24 hours.
The Question, then is...Do you think this should be changed?
Since this is a poll, only logged in people can vote. The list of people who have voted, however, is only available to me (and it's not like I'll be checking it). Still, I understand if you're not comfortable with that, and feel free to leave anonymous comments registering your opinion below. Do know that I'm going to go mostly off of the poll results, though.
Should the length of time the prompt freezes last be changed?
How so? (Select all options you're in favor of.)
Keep them the same.
Keep the two intermittent freezes around 24 hours but lengthen the between posts freeze to two days.
Keep the two intermittent freezes around 24 hours but lengthen the between posts freeze to three days.
Keep the two intermittent freezes around 24 hours but lengthen the between posts freeze to more than three days.
Lengthen all freezes to two days.
Lengthen all freezes to three days.
Lengthen the two intermittent freezes to two days and the freeze between prompts to more than three days.
Have unfreeze happen only when the filled prompt post is up to date.
Make prompt freezes based on number of pages of prompts and unfreezes based on number of comments.
