over 18 years of age to the service to create their own accounts. This was
suspended the next day due to an "insane demand" for accounts. On August 6,
each Google+ member had 150 invitations to give out, but on September 20,
2011, Google+ was opened to everyone 18 years of age or older without the
need for an invitation. After Google+ went public, users registered to Google+,
