Our conference call sessions are toll-free within the U.S. and Canada.  Several international participants have been able to connect toll-free using Skype for a VOIP connection, which we now recommend to others calling in from outside the U.S. and Canada. 
 
First, you'll need to establish a Skype account at www.skype.com.  Once Skype is set up and functioning correctly the only thing that is different when connecting with our "Thinking Roadmap" conference call sessions ("OD" or "The New Economics Study Sessions") is the use of a pass code and security code.  For our "OD" sessions, these numbers are provided once the "participant survey" is completed.  For the "The New Economics Study Sessions," these numbers are provided in an email from Tim Higgins, who hosts these calls.  In either case, when prompted by Skype to enter these codes, use the keyboard not voice option and be sure to turn off the computer's microphone, otherwise the numeric keys don't function.  If the microphone is left on when the codes are entered, Skype's automated operator will reply with "number not recognized," as no number has been transmitted.
