Delight at finding the OU has activated G Suite for education. I am well through training to be a Google Educator Level 1 (Certified). Its impact and benefits are huge, not least replacing most the of current platforms used by the OU.
This is my account - activated 9 days. I have been Google since the start, transferring to Docs, Slides and Sheets to rid my life of hideous Word, PowerPoint and Excel. It has grown gently from a basic and easy to use set of Apps, to a suite of simple to use, intuitive and connected tools that create the most versatile of learning set-ups.
'Sites' the blog platform could see off this environment I am working in now. This would be a mistake. I rave to colleagues about the affordances of this space because as well as being a blog, it is really a threaded conversation too.
You can always find someone to talk to
