Looks like this will fast become a great pyro resource.
Ned Gorski, who I'm sure many people know is a PGI grandmaster, owns the site and along with a forum there are articles on pyro related topics, a formula database
and safety videos.
New and growing but in my opinion worth the small subscription to join.
