I would like to create a page upon registration on my site based on user name, e.g.
My concern is though it’s need to be unique in the most user-friendly way.
E.g. you could add
john-doe-2 but it’s not cool for second John Doe (“why am I second?”).
How can I make sure it’s unique? I’d still want to have name in URL. Should I add a random number? How small should it be?
Is there a better way?
