We posted a note about it in early February, but the web host for 24HCD sent an email by mistake to hundreds of our event hosts and participants.
The email asked hosts to "renew their membership" and asked them for a form of payment.
This email was an error and all hosts and participants should disregard.
We are not, and will not, charge for official participation in 24-Hour Comics Day!
24HCD administration is completely run on volunteer power, and it has taken our volunteers weeks to respond to the worried emails we've received from hosts.
We apologize for issues that this spam may have caused--you'll never receive a valid email from us asking for money for hosting this event.
We appreciate all of the event hosts who make 24HCD such a successful and fun event for cartoonists around the world!
