I like that it has all my contacts in one place so i can see who's available for projects at any time! Also have an option where you add your own notes which makes everything more organized as well!! The only thing about this software its not very user friendly when adding new people or if they change their email address/name etc..
Not sure why but there are times were things don't show up correctly also sometimes emails get stuck into limbo state until deleted by me manually. It helps keep track of everyone involved within our department especially those individuals we work closely with often multiple times throughout out day every week/ month ect.,.
