You can add as many of your colleagues as you would like to IdeaStream.
To do this go to IdeaStream and find the event you want to invite them too.
For instance a Bitesize video on "3 principles to drive strong curriculum leadership"
Then on the right hand side click "share with colleagues"
If you can see your colleagues name is in the list provided you will just need to click their name so they have a tick next to their role and then "send email" which will invite them to watch the video.
If you can't see them in the list you will need to click the blue link labeled "this link" in the "not listed above" paragraph.
