I like how easy it was for my team members who were not familiar at all about Project Management software or tools - they could get up & running quickly! The interface can be somewhat confusing when you're first learning where everything goes (i'm used now). It's been great having one place we go together as far as our projects/tasks have gone since starting this year!! We've also had some benefits from using PMP training online through them too which has helped us learn more ways of utilizing Pmptools better than just doing what comes out by default without knowing why its working differently then other programs etc..
