Im sure the sleuths have already been all over it but thought it was just bitcointalk he had used to communicate
adam and satoshi never communicated on this forum because adam didnt sign up to this forum until 2013, long after satoshi left
satoshi's communication with adam was just for citation not creative collaborations
so nothing exciting.
the reason its become suddenly relevant. is due to the COPA vs CSW case where adams involvement came into question
