Nice to hear you're doing well.
(But I'm not a mind reader. XD )

Now, on to answering your questions...

"submit more than one picture in our category"
Huh? I don't think I said that... unless I misunderstand you. In any case, try e-mailing your fan-art/s as an attachment. My e-mail account has practically no size limits.

"I post the original in my LJ and deviantart accounts and in NarutoForums"
You are the rightful owner of your art, of course. I have no problem with that, but please wait until January 1st to post them personally. I would like the calendar to be new and fresh for everyone; if someone sees a fan-art and goes, "hey, I've seen that before. This is just a bunch of recycled stuff," then they would feel cheated. Plus, it could be mistaken as a 'pirated' fan-art. I don't want that to happen.
So please, wait until the calendar is released. You are free to do whatever you wish, afterwards.

Thank you for asking these questions. It helps a lot to talk things out and clear things up. ^^

I look forward to seeing your fan-art,
