MOOC environment

Every MOOC is different. Because the structure of this MOOC is highly collaborative and project based, we have chosen to use an open, distributed learning platform; that is we have used a variety of different open platforms including Google+, Cloudworks, Slideshare and YouTube etc to support collaborative learning.
From the information many of you gave us, we know that on the whole you are an experienced and technologically confident group so you might well have already established tools that you would prefer to use and that's fine too.
