On the toolbar (the little blue line where you can add to your playlist, print, play, etc.) there is an add to group button that you can push. If it doesn't allow you, you may have to change the privacy settings on the board to either everyone or all in my organization (from the wrench toolbar icon). I have a video how-to in my sway to reference...I can send that out as well!

So, I was having difficulty putting some activities I found into the group. What I then figured out was using the tool icon-it looks like a wrench maybe? Once I clicked on it, and scrolled down there was an option that said add to AIU8 group and when I selected that it uploaded it to the groups activities. Are there any other ways to download or share activities, or am I doing this correctly?
