Who can create similiar plugin like this ( because this plugin is not updated): http://dev.bukkit.org/server-mods/korn27a/ Sorry for my english
What would be the difference though? If you just want a similar plugin without listing any differences, then just download the plugin.
EDITED: http://dev.bukkit.org/server-mods/explevelgive/ It isn't approved yet though, and when the download gets approved, you will be able to download it hopefully.
