I haven't enabled user notes for users, I don't see anything about Icash in the user notes section.
However when I enable the postbit edit, it will be displayed in postbit. I use postbit_legacy (profile left of posts) on my forum. I can't tell if it also works if you use the normal postbit (profile above the posts) on your forums. Or the other way around I always confuse postbit and postbit_legacy.
