Well, I don't know if something like this is possible.
I'm playing on a server and the admin says he's working on something like this, but he doesn't know if it's possible.
We want to introduce a secondary industry and because most of the players won't stick to the rules. For example if someone needs a chest and the carpenter isn't online, he will craft the chest himself.
The plugin should prevent this.
(I hope you understand what I'm trying to say, because I'm not a native speaker :smile.gif: )
You might check out bukkit, I'm not sure if it has the granularity of permissions you're looking for.
I know that you can limit many things with bukkit and it's plugins, I'm just not sure if it can do what you're looking for.
As far as I know, you just can blacklist items in general but not for certain oppucation groups. In fact I am a total noob in the matter of modding and programming yet so I don't know if it's even possible to create a mod/plugin which allows an admin to blacklist items just for few players.
It is quite nice, but not exactly what I'm looking for. We use this to prevent miners from cutting down trees.
But players should have the possibility to place their doors and staris etc themselves, they "just" should not be allowed to craft them themselves.
