Thanks, this is so helpful to know! I had no idea I could've do both, self publish and add to publications. I know some don't accept already published material. Do you know of it is possible to self-publish and submit to more than 1 publication, as I know medium have certain rules about publishing same article multiple times? Maybe self-published articles are only allowed be republished in 1 publication rather than many? Would love your feedback on this. Thank you.
