I do have copyrights with deviantart I believe, but I have no clue what a creative commons license. I read the description, but I'm still not sure.
No, look at your comic again. There's just a comic.
My point is... you're representing nothing except the Slashers themselves. You're not representing yourself, because if I repost this somewhere, nobody has any idea who made it. I would just put a (C) Alex Martel 2010 in the bottom corner. In addition, if FE is the primary site you're promoting with this (which you've said many times it is), promote the site. Just put an "
http://www.fight-evil.com" somewhere, probably in the opposite bottom corner.
A Creative Commons license is basically a formal way of saying how you're willing to share it. DeviantART walks you through the process with each new submission there, check it out. For example, a standard webcomic license is an Attributive-Non-Commercial-No Distributive Works license, which means that nobody's allowed to make money off your work, nobody's allowed to edit it and share it, and anybody who shares it is required to state that you made it.
