Tom S,
It appears you're defining the word "sponsor" in a very narrow financially-related way. My Webster's first definition of the word "sponsor" says: "A person or agency that undertakes certain responsibilities in connection with some other person or some group or activity; as in being a proponent, endorser, adviser, underwriter, surety, etc." Taken in the broad sense, the RVForum endorses our rally activity and its responsibility is to allow us to talk about it on the RVForum.net. In other words, the RVForum is a backer of our social activity. In the early days of both FMCA and Escapees, they were loosely-formed groups of people who were all volunteers, just like us. Now that they're so large, they have paid employees and member dues help underwrite their rallies, as well as the fees members pay to attend.
So, I definitely believe that the RVForum sponsors our rallies even though they are all done by volunteers. Without the RVForum we would have to find some other place to advertise the fact that we're having a rally.
