http://dev.bukkit.org/server-mods/blockprotection/ Any plugin for R4 similar to this? It's perfect for what I want, just a little outdated.
PreciousStones can do this. Although PreciousStones is really messy and you have to disable lots of junk in the config, to just get basic block protection functionality. http://dev.bukkit.org/server-mods/protectionstones/
PreciousStones doesn't require WorldGuard. You can disable that area protection and have it protect block per block.
