Thanks. The course I did covered the same skills and techniques you talk though, but seems to be more image based. I see now that the skill of fully visual facilitation is hugely complex. I tend to doodle on a whiteboard when I am facilitating business meeting, but not sure if it adds anything. Hence why I want to spend some time now to learn to take visual notes for myself, also to build my own confidence to try more things on the whiteboard.
I didnt connect to Google+ for the last session (still a little too shy and feel behind the curve of the existing class) but will do next time.
