Well, it seems that our software sent a birthday greeting on January 1st to every member who did not enter a birth date during registration. (If you don't beleive me, just look at the bottom of the first page.) The default birth date in reistration is January 1, 1901.
Just so you know, it was planned that way. Thousands of our members appear to be 108 years old today. We wanted to be sure our bases were covered and that everybody got at least one birthday greeting this year, regardless of your actual birth date.
