Take advantage of the dissent in AMHR right now - there are MANY people in AMHR who are unhappy - at Nationals it was obvious, everything from the Shetland influence and prevalence ot the measuring (there were some BIG horses in both divisions). If AMHA could take advantage of that, they could gain many members. All the things you are talking about are ways to take advantage - lower fees, more shows, etc., but probably the biggest is for AMHA to ACTIVELY WELCOME new members. Whether justified or not, when talking to people about why they stay R and not A, the attitude of the members is the biggest reason. I've been told AMHA is more "snooty", "snobbish", "arrogant", and a number of other terms, by not just one or two but dozens of people. Whether this attitude is real or just a perception, it has to change in order to really grow the organization.
I'm in an area where I could easily attend multiple (at least 3) AMHA shows a year, but don't. I have both overs and unders, and half my horses couldn't show A. For me, I can really only show one registry, so it is the one that all my horses can show at. However, a lot of R breeders are concentrating on unders, as with the Shetland influence in R's, many breeders who don't want to "go Shetland" feel they can only be competitive in the unders. THOSE are the people AMHA needs to target!
