"I have access to the best minds...": was BAD, BADD, PIANO

[Jason Kanter]

Robin Blankenship said: "One thing that you might consider communicating to 
either this or future customers that have difficult pianos for you is that 
you have very quick and firm access to some of the very best minds in your 
profession through this list."

Good point, worth doing. But: I have had a bit of a stumbling block in 
talking to most people about this: simply how to describe the list! By far 
the great majority of people, even the internet-savvy, do not readily 
comprehend what is meant by a "list." If I speak without considering my 
audience, what comes out is something like "I'm a member of an online list 
of piano technicians" and they visualize some kind of printed list, like a 
membership list - nothing like what we want to convey! - which is basically: 
if I encounter an interesting technical problem, I can post a question about 
it and within a day I will probably have half a dozen expert responses. This 
explanation is hampered by the word "list." How can we quickly describe what 
this is - this cyberspace gathering of great technicians, this watering hole 
regularly visited by many highly esteemed individuals from all over the USA 
and Canada, England, France, Netherlands, Norway, Australia, people willing 
and eager to help share their expertise. But instead of conveying this, I 
often find myself trying to describe what a "list" is - automated mailing of 
emails to everyone on the list, yadda yadda yawn.

Has anyone out there a great way to explain what a phenomenal resource we 
have? Some analogy as powerful as "it's like tuning forty guitars"?
