Glad I'm not the only one clueless about this particular topic. Guess a possible mitigating factor is my late start -- I graduated from university before Google even existed, in fact without ever accessing the public Internet. That's right whippersnappers, if you needed to know something back then you had to look it up in a book or find an actual human being with the required expertise. Crazy, I know.
Erm, in regards to that last point, if any HC members did feel moved to (privately) point this old dog in the direction of locations where our common interests are pursued, I'd certainly be willing to try out some new tricks.
