Second name text is commonly used to give club name and or cat level. Not really the best way, isn‘t it?
Why not maintain the popular clubs with their official design and every Zwifter can optional sign in / or request to join a club?
While riding for a club you could automatically see who is zwifting currently without necessarily follow all individual riders of your club. You can ride any jersey but still get recorgnized being part of a cycling club. In races you would more easily identify team mates for tactics, many more benefits I think.
