UBB.Developers Forums UBB.threads 7 Development How Do I? Promoting some users

I would like to promote some users. To be exactly, those who send anual donations to the forum.
My ideia was adding a flag next to the user name, in the same way we have "A"=administrator or "M"=moderator I would like something like "D"=donor ??!!
I read this thread : https://ubbdev.com/threads/php/...ew=collapsed&sb=5&o=&fpart=1
but it looks like I have to change many files, in many places. I was just wondering if there is any simple way to add a flag, or make the name apear in another color (also like moderator) or any other way to promote one expecific user.
I can mannually add it to her/his name.
Any ideias?
