Free Tools for Online Collaboration -- Google Docs

At the PulseWire office, we use Google Docs a lot. It's a great way to share files without bogging down your inbox, and it allows you to access files from any (internet-enabled) computer without having to deal with messy e-mail attachments.

It may be just the thing your organization needs to make information sharing more efficient. And it is definitely a great way to collaborate with other PulseWire users off-site!
