The answer is yes! However, Google Plus is not activated automatically, each institution has to apply to Google in order to have Google Plus enabled. We have applied for the ability to turn on Google Plus for the University domain and are now waiting for the Google process to run its course.
Once we have the ability to activate to activate Google Plus we will test it for a maximum on two weeks and if it does not cause problems for our existing services we will enable it for students and staff. As yet we do not have a set date for its arrival but will update you as we learn more.
