I am considering Volgistics - using the 30 day free trial to become familiar. If anyone uses this program for a volunteer group of 200-500, would you be able to give me a statement regarding the effectiveness, ease of use, and length of time you have been using it. I would also appreciate any other information you may be able to provide that I may use to "sell" this to the "powers that be". If possible, can you reference your hospital. Thank you
