This has happened many times, I see a post which is fairly big and un-readable. No problem, the OP is not English and I can help. To get half way through when I see a notification telling me an update has been made!
When some one edit's a post, can it be locked to prevent others from editing the post at the same time please?
As per the post Lock a post for editing, or at least display a warning I don't think a warning is acceptable personally because it allows people to ignore it!
