Just out of curiousity, I did a search for all the tube groups at Yahoo and came up with a whopping 693. Some contain only 5 or 6 members but there are a number of big ones - the highest membership had 2,391 members. This is what you up against...then there are the mailing lists. There were even a few groups at Yahoo where you could only be 'invited' to join...wonder what they're passing around. :) Irene
