Fellows, an alternative that people might want to consider is to rename the group that is organizing. If people prefer to keep the current subgroup in power and then go from there, then how about simply renaming the group from "Squeak" to something like "Islanders Squeak"?
That would make this question of who is represented much less important. It would be that group's project, and whoever wants can join in. Whoever does not, can do their own thing.
Heck, even if it is supposed to represent the larger group, calling it something like "NetSqueak" would seem to make sense. After all, it's no longer the same project that Squeak Central put together and maintained.
Anyway, any organization called simply "Squeak" or "the Squeak Foundation" should surely strive for broad membership from existing Squeak enthusiasts. If that's to be the name, then be prepared for a harder problem....
