No real rules there. As long as it's on topic, then you may instantly pin Kira art; cosplay pics; fan-fiction links; commentaries; screen-shots; merchandise; links to your own group or community; photographs of your Kira crafts; or whatever else morally, ethically, musingly or amusingly takes your fancy to do so.
It's like our Death Note Month of Light Yagami every day!
However, if you want to speed things up, either comment before with your Pinterest name and/or a link to your profile, or else post the same privately via the form on our Contact Page. The first person to pick it up will rush in and get you instantly up and running.
Incidentally, it's not just Kira Pinterest Boards that we're hosting for the community. We have a growing number of other Death Note character boards, not to mention many other categories of Death Note boards on Pinterest too. You can hop onto the majority of them as contributors - and/or all boards as followers or folk merely breezing through, passing a moment or two looking at the pretties (then wondering where the last hour went).
Same drill as before, if you want an invitation to any Death Note News Community Pinterest Board.
