Create a simple attendance check block in your Proclaim bulletin in addition to the contact card
Attendance is a difficult task. We can use a third party app, but if people are already logging into the bulletin then they could simply click a box to say that they are present for worship. It would actually be best to prompt them when they log in rather than hiding it in the contact page. The checkbox would need to be linked to the administrator so she/he could work with the data week after week.
