Are there different notes for each card? or each person? when do they delete off the account?
No there is no different notes for other cards, MR has their notes. but definitely each person separate. So even though they would not delete it, it's impossible to look thru 20 or 30 notes when a person is calling in, they usually look thru the last few notes. YMMV.
Actually, thats the reason why people are able to get 2 or 3 platinum's, and would they look thru all the notes....
