Here's an interesting one:
New Software.
I was here during those early days, but didn't register until June when I needed to ask a question. At that time, it only took a few minutes to read every post every day. I can't do that any more, so have to concentrate on my favorite forum - Diesel Discussion.
It's may also be interesting to note that there were no separate sections in the early days. Everything was in one place. When the split took place, Bill and Donnie wanted to have a section for discussing "Is Mercedes too troublesome", "Is there a forum like this for Lexus", and other stuff like that. They never planned for the Open Discussion section to become what it has. Just look at the description for Open Discussion - "Discuss anything you want to here including cars other than Mercedes." It was supposed to be all car related, and for a while it was.
