We have CiviCRM install with a group, used for newsletters, and some event registrations. Our customer added a checkbox to the event registration profile to subscribe to the neweletter.
Now, when someone already subscribed to the newsletter (added to group 'newsletter'), uses the event registration profile but not checking the checkbox to subscribe, this results in an unsubscription (removed by web).
My question: how to avoid this (evidently unwanted) behavior? And how to allow people to subscribe in a better way to subscribe to a newsletter from the event registration form.
Thank you!
