Mormonism enters the world stage as a major religion by 2010

[Hnau]

I'm thinking a membership of some 210 million by 2010, which is 15x its OTL numbers. So how would this be accomplished? I'm thinking all of its controversial aspects being removed from the get go would give it a much better name. I'm talking about polygamy and black discrimination... a non-polygamous Mormonism with an openly abolitionist platform as well. What do you think? Just the seed of an idea.
