Using Odin's script idea I came up with a few more options for a scripting language. Here they are:

Syntax: /choosemusic
This would automatically make a list appear in JJ2 that would let you choose from music files that you have in your JJ2 folder.
example: /choosemusic ChrisiLiz.it (You don't have to type this. The client will choose the music through JJ2)

Syntax: /levelvote [Levels for Voting]
This would automatically make a list full of different levels to vote on. The list would appear in JJ2.
example: /levelvote sfalls2.j2l xlmjrc.j2l olcunder.j2l
