I have not heard of the organization. Everybody is starting an organization so they are virtually impossible to keep track of them all. The major ones that I know pretty well are:
WABDL- single lift bench/deadlift, tested, doubles and denim are allowed in shirts, single in deadlift suits, Pres -Gus Rethwisch
NASA- tested single ply only. 3 lift, single lift, and strict curl. Pres- Rich Peters
APA- Mainly untested and some tested, doubles and denims allowed, single and 3 lift, Pres- Scott Taylor
USAPL- single ply, tested
APF- Mainly untested and some tested, doubles, denims and canvas allowed, single and 3 lift, Pres- Ernie Frantz
There are a ton more and rules occasionally change. Good luck
