Bukkit:about tab complete

Alright, so I found out after giving players the permission node "-bukkit.command.version" They cannot do that anymore

 

You can download a plugin to stop this from happening

 

Plugins aren't needed for this. It just takes up an extra plugin slot for no reason.

 

That might be true but a plugin can block commands so people who know the plugin can't do the command and the person who did the command knows the plugin they are using
for Example: someone does the command /pex and the permissonEX prefix comes up they know what plugin you are using for groups with a plugin it will say unknown command
