Cheers for the reply, Zandor.

I guess the middle ground would be unlimited time to edit your post.
It didn't seem to cause many missing posts at Overgrow. Once in awhile you might have to scratch your head and figure out what had been said due to a post having been edited to nothing, but that would usually only happen in the Lounge rather than the Grow forums. It's the Lounge where we usually fly off the handle and say something we later regret and want to remove.
