Sort of.
Some of my inking, pencilling, writing and editing has been published by CFCA, but it hasn't been widely distributed. I edit pretty much every bit of text we produce, including the Blackwing 1.5 comic and the Seadragon CD comic we released at the last Supanova.
I haven't personally published anything of mine (the 'thankless task' aspect of doing so is a bit of a deterrent

).
Heheh, if I wrote the Punisher, just about every story would involve a politely written letter from Frank, to the 'bad guy', detailing how he can either cease and desist, or face the consequences. The consequences being supported by quantified proof of the ability and intent to enforce them. Then when the 'bad guy' inevitably rejects the advice he has been given, the rest of the story would involve a lot of sneaking, abductions, arm breaking, bomb-setting, and laying prone in the bushes with an MG-42 and/or an RPG-7, awaiting the double-page-spread-montage of 'bad guys' being torn to pieces by 1200 rounds of 7.92x57mm per minute, from 'Hitler's Buzz-Saw'.
Would anyone buy that? Surely it would be worth it for the [BZZZZZZZZZARRPPP!!!] sound effects alone.
