As far as I know, the basic pointers are people who have signed up for the lessons, whilst the champagne glasses are people who are paying money.
Is it possible to search for members on this site, if they haven't posted on the forum? That seemed to go hand in hand with the idea of the map. And the names seem to be the ones from the old site.
Sionned does not seem to be as active on this site as she used to be, so I don't know if anyone is keeping the map up to date.
This is certainly not a complaint, just a statement that the map doesn't seem to be playing as large a part on the new site as the old, so it isn't kept up as much as it was! All the hard work done has to be rationed out in the most effective way, as it were!
(For what it's worth, I never got back any answers from enquiries or advertising our group to people through the map, so I'm not personally that worried about it not being of use in that way any more. [I'd often find I'd been sending info or adverts to people who hadn't logged on the site in years!] Other peoples experience may vary, of course!)
