When you ask for a slot in the comments below, I will assign you a list number. You are free to change that part of the user's ScratchPack, and it will be your own part of everybody's savecode that you will able to use however you want.

List Spots(50): 1 - @MyMessage ??? 2 -oxiti8 3 - 4 - 5 - 6 - 7 - 8 - etc.
