I have installed a voice messaging system for the podcast. So if you like, visit the show website, scroll down, and underneath the Frappr map is a widget that allows one to phone call messages to the show. Messages left do not instantly become publicly listenable, but can be played via the widget once they have been approved, and your message may even be played in a future episode of the podcast!
