Mark Pottenger is Dr. Zipporah Dobyns’s son. He has for sale an Asteroid program to supplement your main astrology program as none have a full listing themselves. Serennu.com does provide for free a good account, but to get all that active that day you must pay $69.00 per year. Pottenger’s version is $100.00 for 20G worth of asteroids that you never have to upgrade unless you are a real asteroid junkie. See information from Mark below and if you contact him let him know we sent you. We could use the exposure. Other than that, we have no financial stake in this enterprise.
