Everyone has been forum user, it's just to find out differences between all users (users who have never been anything else than users, and users who have been mods or admins)....you can choose multiple choices.
Divided between different color/groups, thus the quite large group of "blue moderators".
It's not only currently role(s), but since you joined this forum. People who are mods or admins would also vote forum user, it's to find out % of users who have had a role other than a user.
