Make sure you DO NOT!!! have the most recent version!
The most recent version of Skype is full of bugs and has so many features that simply do not work!
I updated skype on my comp recently and it now will not let me find a new contact! I had to log in on my wife's laptop to add the contact, in order top take an online interview!
Seriously, they need to fix all the bugs or revert to the previous version!
