I've been hearing a bit of hype around Skype this week, which sounds like a pretty cool idea. Free download, make free phone calls, etc. Being a bit of a paranoid, I decided to actually read the license agreement, and found this paragraph interesting
6. Payment.
You acknowledge that certain functions in the Skype Software are only available to paid subscribers after a free trial period of the Skype Software and Services (the "Free Trial Period") ends. After the Free Trial Period ends, you will be presented with the option to subscribe to the Subscription Services. If you do not wish to subscribe, you acknowledge that you can not access functions and services only available to paid subscribers. To subscribe to the Subscription Services you must agree to the terms and conditions of the Subscription Services.
It's interesting (although not surprising unfortunately) that I couldn't find any mention of this bit on their website, like what parts aren't free after the trial period. So this would be free phone calls as in free sample, not as in free beer...
TANSTAAFL I guess. (If you aren't a big enough geek to grok that, ask a friend.)
