I don't know about members but I had zero knowledge of the promoting until I saw a girl i recognized and was like, "hey whats this??" but then still spent less then 5 mins. I dont really see it as worth it, but depends what you have to do. If all it takes is being nominated by your members, then go for it! I thought it was like, "donate some of your earned tokens and get this promotion!" which I wouldnt.
Good luck if you decide to!
