Bukkit

v1.1:

• Portcullis "knocking." You can now grant players permission to open your portcullis from the other side (and you can automatically do so). Only works on a portcullis created with this version or higher. Usage: /baportcullisknockallow [playername] and then left-click a portcullis. From that point forward, that player can open the portcullis from the outside by left-clicking the portcullis. To revoke their permission, /baportcullisknockdeny [playername] and then left-click the portcullis.
