It just means you donated to the site after you were already a friend.
It's all just randomly generated
Huh... I don't think that happened though? Or I donated right as I was made one or something. I don't wanna be a fraud in that case haha.
Contributor is for people who donate $20+ and ask for the status. Friend is for people who have been around a while and who an admin likes enough to flag. They aren't related.
Separate names with a comma.
