bad horizontal referral ?

[Kevin Darcy]

Examples work perfectly, assuming they're constructed properly.

If you want help on a real zone, you'll need to give the real zone name, 
not an example name.

FYI, myzone.com is delegated to ns1.netnation.com and ns2.netnation.com, 
neither of which appear to be giving horizontal referrals.
