The best way to get started is to try the software. Invite some friends (you can do this from inside i pathmaker) to try it with you, so you can appreciate the team and group support features.
Follow the link below. It takes you to the application. You can register as a new user, and use the application for free. If you like it, you can subscribe online. If you don't, you don't have to do anything - after 30 days, your User ID will be deactivated.
