A colleague and I have recently started up a website devoted to the (professional) use of simulations in teaching and training on peace and conflict issues. You'll find it here:

If anyone has suggestions for additional links and material, I would be grateful (keeping in mind the intended audience: aid donors, NGOs, international organizations, the military, and post-secondary education). Suggestions can be emailed to me (you'll find my email on the website) or posted here, rather than as comments on the site (which we would prefer to leave free for professional discussions).
Thanks!
