This plugin that I made a bit over a month ago, gives new players, or well, silly ones, a grace period after they join, where they won't drop their items, or xp when they die. I originally got the idea to do this, when I had players on my server dying over and over again, but I didn't want to enable keep inventory for everyone, since I felt that would make it too easy for players that are already established, and skilled at what they do.

See the documentation tab for more information.
