Thanks Terijo. I keep copies of all my work on either my notes app or Pages (saved to the cloud), which are usually dated to the date of final draft. In any case, the publishing date on Medium of individual stories will also provide proof. I guess it’s more the wider question of what name I want to be known by in publishing — I initially choose my Medium name (which is actually my real name, sans surname) in an attempt to evade Google searches from my day job (in the law, but not intellectual property), but I never really thought about where it all might lead…
