I think Sirref had asked for that, and I declined.
Some MOTM winners choose to keep their username color the same, but most opt for the orange. The issue with multiple colors is that it is tied to a usergroup (can't have multiple user colors per usergroup, not my design, don't blame me!
) So if I were to create another usergroup just for those MOTM winners who wanted Green instead of Orange, I then need to make sure that additional usergroup has all of the correct permissions across any change, feature, or forum that is added from that point forward. It's a whole bunch of extra admin work for very little benefit.
