In honor of my 100th post, thus making me a Senior Ledgie...
I'll respond to anything I find interesting (if I have something to contribute back that is), no matter how many posts a person has or their join date. On that note though, there are people that currently post so frequently that I wouldn't even know they weren't Addicted since I'm used to seeing their name. In the same vein, there are people with thousands of posts that I've never even noticed.
One thing I'm curious about is, when searching old threads, I notice regulars from years ago that have thousands of posts that never post anymore. I wonder what happened to them. I noticed the three top posters haven't posted in over three years.
