Recently, I was looking at Dungeon Defender questions when I noticed a slight inaccuracy in one of the answers. The ETA of a patch. It was originally the 7th, but had been changed to the 9th. Unfortunately, a simple change from "7th" to "9th" wasn't allowable. I had to edit more!
I ended up just using the long form of the date to get around it, but such a system seems unnecessary and arbitrary when you have to have a high amount of karma to make edits without approval.
