I like that we can access it from anywhere with an internet connection so our ministry is able to be more efficient in reaching out into new areas for Christ's work! It has been difficult at times getting used to all these features but when i do get use to them they are very helpful.
Also if you need support there are always training sessions available as well which helps me feel less overwhelmed about not knowing how something works or what feature does exactly this thing. The only improvement would have nothing really anything wrong just small things heren'there such as adding some options/features within my account area (maybe add another option similar to "My Profile" where users could store pictures).
