I don't think the original message board postings are still up. I Googled but didn't see them. He appeared on a message board and had a single (very long) thread over the course of a couple months. Then disappeared, no one has heard from him since. If you (or anyone) want to read it, PM me your email and I will send it over. It is a 1 MB TXT file. It's html formatted so just resave it as a .html and open it with a browser.
It really is fascinating stuff. Very detailed if a hoax. He came "supposedly" from a timeline where civil war broke out in the US between 2005-2012. Which obviously isn't happening, the out he is given (by supporters) is that he he was in 1977 and revealed that the Y2K bug would happen. Due to the warning, we were unaffected, but his timeline was thrown into complete civil meltdown in 2000. That is the difference.
To much to explain but well worth a read. One thing worth noting, he predicted Mad cow disease before it happened. I don't know how. He also knew that The IBM 5100 had some sort of programming capability that know one knew of at the time. IBM held that info back because in the 70's that machine was a fraction of the cost of a mainframe. It was the only somewhat portable computer ever capable of doing what he needed it to do (fix the UNIX time bug that will occur in 2039).
I also had a thread on this a few months back if you want to check that out:
