I know you guys have been making use of Skype lately, so I just wanted to make you aware in case you weren't already.
Skype has gone out of beta and version 1.0 is now available. It is still free, includes some new features such as file transferring, and includes the ability to pre-pay for outgoing calls to actual landlines, not just other skype users. Those of you who use linux as your operating system flavor of choice should be happy to know that Skype has gone into beta for that as well.
You can check out the info and download the latest update here. Enjoy, and have fun.
