I just sent a test email to that address and it seams to be working for me, I’ve flagged this up with admin though to look into it further. Can you try and test it with another email address as I often find emails can just stop working for a day or a few days randomly then start again.
We have a chat room you can go in and talk to the DJ’s of the live shows, and there’s ofc the radio forum you can ask general questions in. What is it exactly you are wanting to do?
