FYI, I think the time limit for editing is 1hr. It might change if someone replies? I'm not sure that these rules are written down anywhere.

@Dang, if you see this can we add to the FAQ?

There's also a delay setting in your profile that delays the message but has a max of 10 minutes. There's also the noprocrast setting to help reduce procrastination. The default values let you in for 20 minutes at a time and don't allow you back in for 180 minutes.

I did a s/while/well in there. Hope that's ok.

All: you are welcome to email hn@ycombinator.com if you need something like this after the editing window has passed
