There are plenty of FAQ's on Meta.
But I'm curious - what exactly are the guidelines for editing them?
Can anyone just edit them at any time (subject to reputation restrictions, of course, which are fairly low)?
When should I edit it?
Should I get approval to make sure that what I believe to be true is true before editing it?
Shouldn't someone make sure they're still right after they've been edited?
I would assume that having them be correct most, if not all, of the time should be pretty important, as they're either guidelines for how to use the site, or explanations for how the site works.
