Beechwood Artists are now displaying on the Map search and yes you are quite right this was due to Beechwood not wishing to list any information on your SAA club pages.
When the clubs edit their information on their SAA webpages there is a section that allows you to place the Art Clubs address onto the website, so when somebody does a local club search, it will pull your club into this search.
On this occasion i have gone in and done this for Beechwood Artists, although it may not be the exact postcode, it is the postcode that we have on our system (which is likely to be the co-ordinator) but presumably it is in the same village so it would bring in the same search results.
As discussed previously in this forum thread it is solely the choice of the art club whether or not they wish to use this promotional tool, but as we have seen from the clubs using it so far it is having a tremedously high impact every day. Art clubs are receiving new members and a much higher turn out to their exhibitions and they simply enjoy being apart of the SAA and promoting their work to other like minded SAA members.
