I know that Symbol!! It was a tiny human symbol, with an echo outline, in the translation.
I have read and listened to everything on John Titor I could find all these years. I even studied the confession of the people who professed to making the whole thing up .... and decided I didn't give them much credibility. I have no problem believing in time travel, in some way or form ... there is way too much advanced technology involved in all this for there not to be things possible to rival all we can imagine. When I was so immersed in this, my mentor told me it was possible then, around 2008, to be reversed in age to approx 24 Earth years Physically ... twice per person. Now, of course it is very different IF you want to take the reports seriously about the 20 and back programs. I always have doubts ... my mentor is no longer with us. I had doubts about him at first too. I thought he was nuts! Everything he ever told me, or anyone else, has been accurate, to a T.
