Shoot...
Even more easy is to ask questions at the registration time...
Like my site is a Dodge Cummins support site. So I ask question about the the Cummins engine at registration time. Like how may cylinder does a Cummins have etc. If you a true Cummins fan you would know this simple answer is 6 (six)... But the bots have never made it in the door yet...
So really you don't need to go out on a limb codeing use the tools you already got...
But to the OP I love the idea of sending the bot to another site...

Neat trick but just a bit to much moding for me... I'm not really wanting to chop up the code...
