I'm another one of the forgotten Jews
There's Reform, Conservative, and Orthodox streams. Increasingly, there's also Reconstructionist and progressive: here in NZ the Reforms and Reconstructionists seem to have merged to become "progressives."
Reform Judaism doesn't really seem to exist outside the United States; I attend Reform services when I'm there if I bother to go at all. Which isn't very often, because I'm pretty lax in my observance. I kept kosher for a few years, then reached the conclusion that if G-d really exists he would probably prefer that I be less wasteful and not have enough kitchen utensils for 4 families. And I can't speak or read Hebrew at all. Chanukkah, Rosh Hoshanah, Yom Kippur, and the first two days of Passover is about it for me now
