It is cool that people are “Tagging” their name if they are going to join a group or race event. That way it is easy to find people in your event. People are adding this tag to their last name … Like PAC or ZGR. A better and cleaner way to do this might be to have a “Tag” data field in your profile that you can change. Maybe a 4 character limit ?? This data field can show up on the name list like it does now, so it would be easy to spot people. It works pretty good the way it has evolved. I am sure the Zwift team can incorporate this great idea into the UI.
