    There was a miscommunication in scheduling. As an organizer I'm offering a gift certificate ($50.00) of your liking to those who attended the meetup Dec 19. Please be sure to email [masked] with your information and I'll be sure to send it to you.

    No one there. Waste of time and gas.

    I don't know that it actually happened, since 4 of us could not get close to the office since the doors were all locked, and the organizer was not picking up his phone.
