The Inbox and Private Message functionality has the potential to be very useful. Some issues:
On selecting "Write a New Message", I see a blank field "To" next to a field marked "--contacts--".
"--contacts--" should presumably expand to a list of users who I've marked as my contacts. However, the only way I can find to add to this list is to compose/receive mail from some user.
1) I might like to add a user to my Contacts list for future reference, without actually composing an email to this person immediately.
2) I think of 'contacts' as frequent contacts, and would like to be able to purge people from my contacts list if I don't think I need to have their name on hand in future.
