Thank-you, I hadn't noticed the "Admin" part before (the rest I knew) - it's been a while since the code was broke; I forgot that it said those threads were started by "Admin".
I made my efforts with USAC on this. Oh well. The Late Model & now High Limit threads are interesting (also the part, in the story from Kokomo, about two former USAC champs in the top 5 last night).
