We have 10 multisite churches and we are all using the same F1 account. Our multisite staffs incude a support person who is well trained in F1 and we have set them up as seperate Ministries at the Activity level. That way we can contact everyone at all locations, keep background checks and training consistent and run all our contributions through one system. It is easy to find all the multisite congregations this way and so far is working out well.
