Now Dave and Scott didn't actually register on the same day
Yes, and as I recall, I also didn't actually register on that Dec 1st, 1999 day either.
As I recollect, I had initially registered earlier on Chris Hansen's even older forum (circa 1998), but sometime during an early SZ changeover some of the records got lost and we simply decided for convenience sake to make it Dec 1, 1999.
Either way I guess, I'm a Synthzone oldie but goodie.
