If you lookup members with usernames that have embedded spaces (such as “provision l-3”, “Salvador Romero”, or “Peirre Masse”) you go to a page that says “It doesn’t appear that this user exists”.
<p>Oh! That's true. I never noticed that before. And my notification bell on the upper right side of the page never worked either. Seems I can't change my username by myself. I will contact the support.</p>
