@Slominer,
“Can anyone, anyone, please quote the exact words (and source) of the Lubavitcher Rebbe saying he himself is Moshiach?”
I will say no. No such place. As a (I hope) fairly learned Lubavitcher, who has heard all these arguments many times, I’ve yet to see such a reference. Anyone can come and insert “hints” anywhere they want, but an explicit source (without reading between the lines, or twisting words,) simply doesn’t exist.
