Emailing racing hosts

Depends who it is. Are they not answering message on here?

click on your name icon on top right of page, click on send message, enter the racing name of the person you want to contact... fill out the form... hit send...

Yeah...I'd send them a message first to obtain said email...

who you trying to to contact?

I just sent you a Redline Derby "test" message.   Look for an "envelope" up near your logo/icon in the upper right of the screen.
