One itty bitty thing
Unless you go to Tiki, Messages, I don't think you'd know if you have one. I only know because the system sends me an e-mail message. I think people are opting out of the e-mail messages so it seems there should be something that notifies you that you have a Message.
On my little writer's site, we have Personal Messaging and a little message is permanently there at the top that tells you if have new messages as soon as you log on.
It's not urgent but it would be a nice feature to use.
