Option to change/edit username#52

Would love a setting to edit and change one’s username after account creation.

Would like to have continuity from my Flickr and IG accounts

When i signed up the my username was already taken but in search i cant find anyone with that username! Please provide settings or form to claim the username! So that people like me have one name on all plafform!
Thanks

I can’t tell which one of you is the real anonymous.
