A group within the Linked_in community I just now found. This or other similar groups could have members who would be worth while to communicate with.

Hello -

I've acted on Jonathan's invitation to look into Linked_in and joined
it as a basic (non membership fee paying) member. With something like
100,000,000 members, it may be possible to find some people who wouldreally be interested in areas of music that are very specialized with
not-too-many enthusiasts passionate about them.

Composers and performers with an interest in all the notes "between
the notes." Just intonation, non-12 tone equal temperaments or hybrid
systems. It's all harmony.

There's an image from the microtonalist group showing a math symbol
for the 12th root of two crossed out - kind of cute if it'll show
here.☺ Best Dave
