Can you change it? Mine seems a tad random and I’d rather edit it.
Click on your profile icon top right> click on your name> open the drop down on the left> click on preferences and then click to edit username and save
Is that for my actual name or the lia57 that you can see at the side of my posts?
Users who haven’t posted yet are able to change their username from what I understand. In any other case you gotta carry it with you.
