So, I was looking to upload my first 3d render to the site. I've noticed on a handful of posts that they have a checkmark next to the artist name which is supposed to say that the artist uploaded it here. How do I do that? I've never uploaded anything to E6 before and I wanted to make sure I do it right.

You can request an artist verification here.

You can upload your posts first and then get verified after that. I would rather make sure you have some approvable and relevant art instead of just handing it out to an account with 0 posts.

So, I need more art to upload instead of just one piece?

Just one should be sufficient. The Artist Verification help page only mentions needing to provide your username and artist tag, and the latter of which only needs it on one post to exist. Technically it may not be strictly required, but I assume it would make things easier.

So, upload the post, then verify that I'm the artist?

Upload the image and properly tag it with an artist tag, then send a DM as mentioned in the help page, yes.

I was always curious about that since hearing about verification process. I just assumed that for cases where there's no clear channel (say, private messages on the listed sites to Dragonfruit) on an established site that the artist controls, to send a message from, the artist could just do something using their next drawing or site they own (for say, comic artists with a known site). It was obvious that you could just embed a (possibly invisible) watermark or publish an image before it was otherwise publicly available with followup on your site. I wondered how people who don't actually use any of those popular sites did it.
