I happened to be looking at the Organizer badge, and I noticed that even though the rep required to retag posts is 500, there are many people with rep lower than 500 who have the badge. I wondered if maybe this is because they retagged their own posts, but I don't have a retag option on sites where my rep is lower. Anyone know what causes this?
I don't think it's a question of them losing rep after hitting 500, since one of them is down at 1.
Note: almost asked this on StackExchange instead, since I assume it applies to sites other than just StackOverflow. Feel free to move if I made the wrong call.
