Originally, Crozonia was published as a b/w comic for two issues in 1999. Dan Merisanu and I never registered Crozonia for copyright. Now that Crozonia is going to be back in the public eye (well kind of), I felt it was important to register it with the copyright office in Canada.
For the comic book creators reading this, any artistic work you create automatically becomes your copyright. I don't have to register with the Copyright Office, but by doing so, I get a certificate that proves the date that I published Crozonia and a couple copies will be sent to the Library and Archives of Canada. Crozonia will also be added to the online Canadian Copyrights Database.

As far as trademarking the name Crozonia goes, it costs $250 online to do so. I may decide to do that in the near future if I find the brand "Crozonia" is lucrative enough. We'll find out.
