Hello all... I didn't see this question in the FAQ, but if I missed it there, forgive me... I'm brand new to this site, and would like to post some pixel art I've created for critique/comments... but I'm very paranoid, and before I do, does anyone know what you have to do to claim copyright to your pixel art creations?  Would burning the images I've created onto a CD, then mailing the CD to myself with the postmarked date be acceptable, or is it something that has to go through the copyright office?  Thanks for any help,

--Zach
