No.6 Discussion Board

Ah, so you have to invite them. Good to know. Yeah, I thought about reblogging it there too because it's already there but maybe not too well known ^^

Okay, I'll try my luck and post the letters there with a source attached.

I would like that too. I mean, I find it incredibly sad when artists answer that they don't want their art reposted but I can understand them as well and respect that. Maybe knowing that it's gonna be posted to a sourcing No.6 blog would make them more comfortable.
Okay, I agree with this - delete unsourced art because the original post can still harm the artist by getting notes. If you got the permission or the artist states that it's okay to repost, then make a new post with the source. It's just copy and pasting from there, really.
I'd like to search for the original tumblr post if possible but you're probably right. Sadly. And that would be a good way to approach it. Tell the artist with a link to the post and if the reposter won't take it down the artist themselve can decide whether or not to contact the tumblr staff.

Okay, I'm off creating the new topic now. Let's see if I succeed xD
