Donald:

"TCR" is a time-consuming and, hopefully, never ending project that is done by 3 great advocates of the hobby who have jobs and personal lives to deal with. I think I can safely say that TCR is part of the "hobby" for them. We are very fortunate to have that wonderful chip-collecting reference even if it is renewed only once a year! Me thinks asking them for more would be selfish, although I have been tempted !
