I would love a note system. There are people who I used to be in FCs with who change names who I didn't talk a lot with or I did chat with but then they'd have gone and taken a break only to come back with a new name. Then they'll send me a tell and I'm like who is this person who seems to really know me? I think it would also help those with stalking problems. I almost never send out friend invites to people. It's normally an FC mate or someone I've become friends with or when we have the fish turn in for the summer event I'd be one of those who'd give the turn in for free so someone wanted to friend me because of my generosity.
