Theres more to the site than just the discussion forum. I often forget that myself but if you go to the main page its the second forum listed. Direct link to driver standings thread. Thanks Bill!

Also I noticed that according to this page 233 separate sprint drivers started a feature in Indiana in 2013. Up about 60 I believe from last year but still quite a bit below 2008.

I also think there are a couple races that were run missing like Brownstown Fun Fest and the Klash isnt filled in either.
