skarpi - I suggest you try the Irish Times special about the peace process
It gives a pretty full acoount of the background and the course of events - and the links section will give you access to any number of competing points of view.
This may be more than you want of course. I think you are right to suggest people write via email - public discussions here tend to get out of hand at times, which is affair enough, but might get in the way for your present purposes.
What you might do is post any specific questions here on the Mudcat, asking people to reply by email (or personal message - even if you did sign in as a guest this time).
