The general theory behind a read along would be picking a piece of canon (such as Marvel Adventures: Iron Man and the Armour Wars, The Ultimates, or Avengers: Red Zone), either dividing it up into individual issues or going for the whole thing at once, and then setting a date to have a discussion of it.

So every one reads the first issue of Iron Man: Extremis by Oct 10th, then someone puts up a post summarising it, and we have at in comments. Possible discussion questions?
