I have a comic strip that I've put on the back burner for the last ten years, and now I'm starting to step up the gun a bit in getting it operational. I've reworked the characters, given them stable names, jobs, and places to live, etc. In order to ship it around to folks for possible publication, how would I have to register it with the government? Do I have to copyright the idea of the strip? Or do I have to copyright every character look and character name? This is something I obviously don't know much about, and I want to get it right before I try to sell stuff with the characters on it . Let alone have anyone see any of the strips... Thanks .
