You know all this stress it seems to be causing to get into groups etc and today I find the group activity is not compulsory. So if you aren't finding a group DO NOT stress.

Hello everyone. It's really great to have you with us for The Art of Photography.
We will be starting a team work task later in Module 1. To prepare for the project, please find four or five other students to work with, either by introducing yourself in this forum, or heading over to Google+ Community and searching for classmates there.
You can prepare for the group work by having a look at how Google Circles and Google Groups work. Some information is available by following the links below. In your team, decide which way you would rather work.
The project is not compulsory. Rather, it's a chance to extend your learning and apply some of the principles you learn in this course.
You can follow this link, to take you to the Arts & Humanities page of the community, where you can connect with other students, and create your teams:
