If I had registered when I first found this place instead of lurking for several years, my ID probably would be in the high 3 digits. No idea what my username would have been since it would have been well before I got the dog.
I checked the user id of the newest poster from last night. We are well into the mid 5 digits. That means nearly 90 percent of the posters signed on after I did. Granted, most of them probably hardly posted and lost interest like my wife did last year. But the same probably goes for many of those who signed on before I did.
