I tried the link, it says it's only to report problems or suggestions concerning the web site.
The link worked fine for me, Ciexzy. Very easy and specifically asking for your comments about 'whatever' (they're gonna get an earful!)
But, if that doesn't work for you, please look at my post #9 and follow those simple instructions at: nickjr.com

This includes topics such as programing
and click on "Blab" in the page menu. You'll get a link to write them.
