Rushing through things again. Missed Thing 13 because I didn't scroll down the page. Sigh.
I've used a Wiki tool in my previous job, called Camtools, as we used as the guimes pigs before it was rolled out. I still use it occasionally. We found it invaluable for creating student guides amongst various staff.
However, this Google drive thing looks like fun, and very useful. I've set up a test page, and emailed it to myself to change it about a bit. Again, will need to spend more time on it. If anyone is reading this, this is the link and I think I've managed to set it up so you can comment.
