Ah! I just realised why that "cows" ad appeared in the google ad banner.
It's because of the guest message that appears to anyone who isn't a registered user of Twilight Lynk. Log out or access Twilight Lynk using a different browser that doesn't have you logged in and see for yourself.
Now all we need to do is figure out why it said nothing but "cows"... though when I think about it... it's the best way the grab someones attention to the ad lol.
