Wow, I didn't even know this was going on!
I've downloaded the Checkpoint_01.zip and will have a look tomorrow but from the comments it looks like nothing great so far... everyone is waiting for some serious info to be released that will be game changing.
I do hope the hackers are serious and have real private documents. We all know 9/11 was a big conspiracy.
That's what I've heard so far too regarding the Checkpoint 01 doc. Will be interested to know if you find anything more substantial in it!
Btw, there's now a Checkpoint 02 also.
I was offline yesterday but just checked and the pages have been removed. Did you download Checkpoint 02?
