So the result is between 10 - 11 minutes (I still think it is 10)
I think it also has something to do with whether or not someone else looks at the post before you attempt to edit it?
I think ten minutes is fair; and if there is something that you need to change, just report it to the mods, and we'll fix it for you.
That has nothing to do with it as my orginal question had a post that was quoted in mine changed after I posted a reply. That is what prompted the orginal question.
Did the quote in your post change or just the original post? I think 5-10 minutes is adequate enough time.
Just to know if I may; what has happened that makes this such an issue? I would like to see the length down to say 2 mins or up to when someone quotes it.
