Difficulties arise in finding 4 people from around the world, in different timezones, who have availability at the same time, and can actually show up when its time.
An hour podcast takes probably 5-10 man hours of work before any real editing, not to mention several weeks to hammer out a date and time.
Anyone can get a group of 3+ people without involving me or Madness at all if you don't want (sometimes we are a bottleneck for things). They don't have to even be forum members. If you are on facebook/reddit/twitter/whatever and can find a group of people, great!
Or we can start the standard process here. I'll sound the Plate.
Who's interested in doing a podcast in the next 2-3 weeks? Leave a message here or send me a PM. Obviously Geoffrobro is 1, need a few more.
