I noticed it's been getting a lot of bad reviews lately, although a new update came out today. I have to go on an international trip in a few months and was planning on forwarding my US number to a local US Skype number so family can still reach me without anyone paying long distance or me getting hit with roaming charges (I would also connect to Wifi and get Skype calling plan). I know this should work in theory, but in practice how reliable is it?
