Only problem with things like this, is that if it's not already in a plugin we have, and you don't know of a plugin that has it, it would need to be coded before we could add it.
I'm not sure if we already have a plugin with this, I've never heard of it before.

 

Maybe like a /god command except its temperary for like 5mins and there is a two hour recharge.

 

no.

 

Any form of godmode for normal users, even if very limited, would just cause... problems, lol.

Music would be cool... I think it'd be neat if we could play music discs with that, though -- when 1.9/release is out, at least. Since the discs will be really hard to obtain...
