yep..... Tim is correct

its set for ~24hours or until there is a post by another user after yours.....

24hours is an extreamly long time compared to most forums, I'm on other forums that have 10mins to edit a post before its locked in, that's about the norm from what I see, however, on another forum I'm on is zip - zero - nadda ability to edit a post at all.

we're lucky here
