Bukkit

v1.6

• Changed: Moved SignChangeEvent handler to priority HIGH to give other plugins a better chance to modify the sign content before Billboards applies it to the Billboard sign.
• Changed: Billboards is by default no longer ignoring other plugins preventing sign changes (like anti-swearing plugins).
• Added: Setting 'BypassSignChangeBlocking' (default false), to forcefully bypass other plugins which cancel the SignChangeEvent.

The player signs are still EXPERIMENTAL: The plugins has no sign protection built-in yet (signs can be broken, if they are not in some sort of protected region (this can also be abused by players selling signs in their land)) and players (with the billboards.create permission) can currently transform ANY sign EVERYWHERE to a billboard sign.

These disadvantages make the player signs currently impractical.

Storage is still playername-based.
