Add it here.
Despite the fact I understand why a 'One week old' rule would be put in place, I still found it rather annoying. A post I've seen a while ago is marked as Unknown_Artist. I made an account to add insight as to the artist and original name of the post.
So I will add it here so someone else may fix the tag and source, or I may remember it when I myself can edit it in.

Please provide valid links to both the post here and the original source.

Got it. Source and artist added (the ones you provided) :)
I couldn't check the post on InkBunny (not registered there), so if there's anyone who has an IB account and can check it, I'll leave it that way.

Did you tried to edit the post? As far as I know, the limitation is for posting only.

Oh, and by the way, welcome!

Edit: I found another post from planeshifterlair: post #124046
If you can look for it on his/her gallery I can put the source on it too. (if you can't because of the limitation)

Edit2: Dammit dude! You made go through all of the Ōkami posts! XD

Inkbunny is under maintenance right now so I'll get back to you on that. But yes, I tried to do it myself and got shot down on multiple functions of the site. I cannot comment, I cannot edit, I cannot even change my username at this point in time.

?? You do know planeshifterlair is shenhibiki right? I Well change the tags to suit.

Thank you for the insight, I knew the animation was on FA but could not find it. Either way it was set to "unknown-artist" with no source. Thank you since putting it with "Shenhibiki" tag put it with more of his work than "Planeshifterlair"
