You don't have to. That's what's cool here on BF: nobody forces you to read anything you don't want to. Instead of whining, invest all your precious time an hard earned money and start a KAI only forum site. If it's that important to ONLY discuss KAI, then I'm sure you'll be willing to sacrifice so much. Ask Spark how easy it is. I'm sure you'll all be jumping a the chance. ORRR, you can keep whining.
"Easy"? How many forums have I seen split off from major boards...start their own boards with a fairly devoted following....and end up dying off simply due to repeated hosting issues?
