Looking back at the old threads linked in the first post I see lots of names that are no longer active here. Just by them threads you can see the changes over the years.
In the 5 year thread looks like I posted our member count and total post count. 4 years ago we had 34,000 members total, and 3,000,000 posts. 4 years later we have almost 258,000 members and almost 6,700,000 posts. PC has grown a little over the years. I can't wait for the 10 year thread.
