As you can see from my number of posts, I am quite the n00b here. Still, I think that for those of us on the Minecraft server who are not mods/admins and work pretty hard to get all of our items, we would love to be able to protect our chests/homes from greifers/stealers. I think adding a mod such as Bukkit would improve playing quality for players, and improve management quality for admins and such.
