"Check it" function

I have this game posted as a widget and would like for the 'check it" link to work. I get this message:In order to accept POST request originating from this domain, the admin must add this domain to the whitelist.
How do I do this?

[admin]

Hi Gary -

Just email me the domain(s) you've got your widget running on and we'll add it to the whitelist straight away. Cheers!

Turns out someone was paying attention to Gary.

Thanks Stephen, for whatever you did.
