Great program, cheap rates. There's a lot of bugs, though, and not just in betas but actual releases. Website is safe; the service is the best for long-distance and works out to (for home usage) 35$CAN/year for max. 6h/day, max 50 different phone numbers anywhere in Canada and the United States and also allows for free calling from any phone (excluding cell phone fees that may occur from calling local numbers) to any Skype contact for free. Really cheap.
