From what I've seen, you can edit posts within 24 hours of making them, I
think. Apparently, this is a problem they're trying to fix, and it's been noted in the Comments forum. Otherwise, editing posts is pretty simple--if you see the edit button (I always have directly after posting, sometimes several hours later, usually until the next day or so), click it and it automatically lets you edit your post. Edit it, save it, and you're pretty much done!
