Inspirometer ignores items in the body of your meeting invitation that do not follow its required format (see the advice on in-meeting feedback).
The key advantage of this is that you can provide more information in the body of your meeting invitation without cluttering up your feedback form.
Equally, keeping your feedback simple and straightforward does not restrict you from ensuring people fully understand each item and are fully prepared for their part in it.
Take a look at the images below. On the left is the body of a meeting invitation which included email@example.com in the distribution list. On the right is the in-meetings feedback page generated by that invitation.
By laying out your agenda in this way, you can easily separate out your intentions for the meeting invitation and for feedback on the meeting without duplicating effort.
