Vladimir thank you! I wish I could see that in my search results. Perhaps it is my browser.
Sometimes when I search a specific job or name - I get an interesting hotchpotch of jobs and names. For instance, with the OP, I got a handful of relevant names (either first or family names), but only about five or six of those. With his full name I got a variety of names that were not even alphabetically close.
So quick update : 24h after Valeria told me the upwork team would investigate, I received an email telling me my account has been activated. My friend can now find me with the search tool so problem solved!
I am just wondering why this hasn't been done 2 months ago when I signed up.
