Got custom rank, no idea what to do with it though.
EDIT: The custom rank and wheel distracted me so much I forgot to download the trainer I was after coming to site in the first place...

You mean you don't know what it changes, or you don't know how to actually make a change, or do you mean you just haven't figured out what you'd rather use for a custom rank?
You can use it to change from your current rank of Elder (shown below your avatar) if you'd like.
