Warlord Games have set up a temporary contact email address.
From their announcement:
As some of you might be aware, we have been experiencing a fault with our firstname.lastname@example.org email address. We hoped to have the issue resolved by now, but clearly the gremlins are still chewing on the wires.
If you need to reach us for any reason, please contact us at this temporary email address:
Alternatively, you can always give us a call in the office on +44 115 978 4202. We’re here Monday to Friday, 9am until 5:30pm GMT.
