It's highly configurable and absolutely a must when you use Jomsocial, however the system is very big or smaller as small.
Some words about the support-team:
I had some very special needs and questions and all the people were extremly helpful and very quick in answering and delivering solutions.
I had a special wish from a customer to combine the ARI Pretty Photo Gallery with another addon (not from ARI) and the support helps me very quick and very professionally.
ARI Soft: highly recommended!
It's not that complicated as it seemed to me the first time. A very good help are the video tutorials. They are great and shows many things and ideas to generate stunning forms.
The contact with crosstec is also absolutely first class.
My best compliments!!
