Most of the time, when I have written a post, but don't post it at that moment, it will still be there after having navigated away from that thread or having logged out and back in again. Which is great! Sometimes though, the post I've written, but not yet posted, isn't there when I go back to the thread. Does anyone know what determines whether or not the 'draft' post remains or disappears? Do draft posts dissapear after a set period of time for example? Any info that helps me to understand how this works would be greatly appreciated. Thanks
