TODO comment from #107

# username -> 'data.auth.local.username':
# * Your username is used for invitations, @mentions in chat, and messaging.
#   * It:
#     + must be 1 to 20 characters,
#     + must contain only letters a to z, numbers 0 to 9, hyphens, or underscores, and
#     + cannot include any inappropriate terms.
# * is changeable at '<https://habitica.com/user/settings/site>' 'Change Display Name'

# profilename -> 'data.profile.name'
# *  is changeable at '<https://habitica.com/user/settings/site>' under 'Change Display Name'
# profilename is not really in the .data.auth section of /user.. but fits well here
# TODO: probably better to remove profilename here regardless
