Edmin,
Thanks for posting your question on the forum. I am surpised that you have not received a response, this might be caused by the recent transition of the forums to the new Ideas site. Anyway, I know of several churches that use Fellowship One Check-In for their adult Sunday school. If you would like to contact one of more of these churches directly, call our support hotline at 866-383-2437 and ask for the customer care department (be sure and leave a voice mail with your name, church, and phone number if no one immediately answers). Customer Care maintains a list of churches that have agreed to receive direct contact from other Fellowship One churches and also keeps track of how churches are using F1 features.
