We are trying to get fan tables set up at Comic or Sci Fi cons in major cities. Above is the list for the Western region. We will be publishing the list for the Eastern region soon. In most cases, this will be minimal cost (table and ticket are minimal cost or free).
We have a con kit that can be mailed to you. Please let us know if you or anyone you know is interested: firstname.lastname@example.org
This is the way many fandoms grow; by going to conventions and letting people know what is happening about their show. We received many "Thanks You's" at Comic Con International - people were just so happy we were there to update them.
