Hi! Yes, this is my own content. I just reposted here, is that okay?

yeah, you can repost your own content, no problem.

Uh oh, this is my own article. Am I not allowed to re port it here? I can remove it from Medium if it's a violation.

No, but you need to hold a sign that says, STEEMIT with the date on it, to verify your identity.
You can keep your Medium posts up as Steemit does not own your content.

disregard cheetah, he does that to help curators, we do need the verification pic though
