When you get to the end it shows if you have missed something. I thought I had finished the week but it showed I still had 3 to go. When I checked back it was the first 3 introductions and I had not realised I had to tick them before moving on to the next.

Glad I'm not the only one then, I did that with the first 4 probably just thinking that it was part of intro. and not really noticing those big pink buttons! ... realised though once I'd got to 1.11
I am keeping quiet on there for the moment. 
Me too for now

... and haven't updated my profile yet either, using own name though.
Groom, if the lead educators do comment are their comments featured somewhere obvious or just mixed in with all the others?
I'm following them, so any comments they make should show. They are just mixed in with all the others.
Thanks groom. I'm following them too but haven't received any notifications of any comments.
I did same at the beginning, other than that decided not to try following anyone else as I could see how many participants and comments there were and way too many to keep up with.
With 1.11, instead of a requested comment, I just scrolled down to the nearest one that reflected my thoughts at that moment and liked it and moved on. Have only been looking in on short bursts really and fitting in with other activities, will see how it goes over the weeks.
