Click here and you won't see X-10 ads for the next 30 days...not kidding
That link is actually through the X-10 webpage, it uses a cookie to defeat the ads. I'm not sure if you can keep renewing it, but here are some other ways around it thanks to your good friends at the BattleBots forum:
Steve Judd's advice:
"PopupStopper, from
www.panicware.com works very well also. Blocks pretty much all annoying popups. Free!"
Andrew Lindsey's advice:
"I use the Proximatron.
http://proxomitron.org/
Not only does it block ALL pop-up ads, but you can set it to filter out web banners, as well as annoying browser features like imbedded music, blinking text, and animated background graphics."
Both of these other solutions have unintended consequences which I am not completely clear about.
Enjoy,
Dan
