to answer your question. you would defend the ring belt just like any other title. you would fight the rings mandatory challengers. the difference between the ring and the alphbet soup titles is that ring magazine doen't sanction fights. there rules have nothing to do with the boxing commision or any else. there just a magazine that says who they feel the champ is and who they think the champ should fight in order to keep there title.

basicly there just another santioning body without the fees.
