I like that it is user friendly for my small church with only 30 members in attendance each week! It allows me as an administrator of this organization all things related to our business from keeping minutes/records up-to date etc..
Nothing at present so far but we are still learning its capabilities through training sessions available online or by one on ones with their support team (very helpful). The cost can be prohibitively high depending upon your needs however there may also be free options if you qualify e.g., churches who have never used any type of electronic communication system before such as emailing people about upcoming events will not need much more than what they already do i.e - sending out newsletters via snail mail which would otherwise require them to pay monthly subscriptions just to send emails etc...
