I like that it's easy enough so we don't need any software developers or IT support staff - just us! The interface could be easier/more intuitive but once you get used them they are very good about letting me know what isn' working (which helps when training new users).
It also has great functionality such as allowing providers access via their own computer instead of logging onto ours remotely which makes things much more convenient since there aren;t always internet connections available where our office may not have wifi yet this way everyone gets equal treatment regardless how far away from home people might live.
