# To create a member, all of the fields except the avatar, email, or
# phone must be present.
# * The name must be at least two characters long

# * The major must also be at least two characters long
# If no avatar is given, an image is provided by http://robohash.org,
# which hashes input to pictures of robots.
#
# Should robohash.org ever close down, there are also regular
# default images available to be used.
# They can be found in
