I've been researching and testing out a variety of free project management tools for my new virtual business. After trying several, I've settled on ClockingIt for the time being. It's totally free, with unlimited projects and seems to offer just about everything I need short of invoicing which I do free with Freshbooks.

Some of my favorite features are:

The integrated timer, which instantly adds time to your task or project, that can easily be paused without closing out, and time can even be added manually for work done away from the computer.

There are one-click reports, automatic email notification of progress or tracking if needed and you can give clients access to their projects or even create a forum to use in servicing your customers' questions and/or requests. There's also a chat feature so you can speak with them in real time directly from the application. You can also upload documents to tasks or projects, tho I haven't used this feature yet.

There's not a ton of instruction available, although I've found it to be pretty user-friendly thus far.

Is anyone else using ClockingIt?
