I rarely use Skype. In looking to practice the instructions for people to use to come onto a Conference Call using Skype, I inadvertently

1 - Upgraded to the new SKYPE - don't like it

2 - I unintentionally, evidently, gave permission for my whole address book (from my computer to be on there). I do NOT want this.

Need to get it out immediately. I have confidential info in there.

I am on a MAC. someone said I should look up how to delete sKYPE data from a Mac.
