This is a free project management system. I have tested out the free service and found it to be pretty reliable and fairly easy to use. This is not a trial service, but a free service. The only thing I don't like is if you are not active for a month they remove you from the free service. So just make sure that you log in at least a couple times a month to keep it active.
Thanks for the link! I've started working as a PM at my job and I'm hoping to integrate those skills into a VA practice. Any extra tools that make life easier are always appreciated!
