Question: Air Classics/Warbirds Int contact details

I am looking for the editorial contact details of the magazines Air Classics and Warbirds International. Could anyone help me obtain these details? It would be much appreciated. If you’d like to send an e-mail, you can go to the contact page of my website: http://www.aircraftinformation.info/contact.htm
Thanks,
Guy.

P.S. Anyone know how to contact Wingspan International?
