From the Navigation Menu, click the ellipsis next to the feed you want to share, then click Share. A pop-up window will appear that contains a custom URL for the feed you want to share. Click Copy and paste the URL into an email or other communications tool.
When you share a feed, the recipients will be invited to create a Meta account. When they login to their Meta account, they will receive a copy of your feed that they can edit. Your feed is not linked to their account and will not be affected.
