Ooh, is 'Email #100' referring to that mysterious 2nd ever forum account that nowadays "does not exist"?
I don't think so... Sounds strange for a forum account to have "permissions". Usually, OS users have that, and since it's talking about ssh and Linux, chances are it's a user in the server that was hosting bitcoin.org. Then, in email #103, you can see Satoshi used that to install a file manager:
Thanks, that worked, I got File Manager installed with SSH. I also uploaded a few themes into Drupal. I haven't thoroughly gone through all the available themes yet.
Reading new Satoshi messages gives me chills. I thought every important email discussion was disclosed already.
So basically Sirius was a CS student back then and Satoshi, seeing that Sirius was talented, decided to let him do the website and the FAQ?
As I perceive it, Satoshi saw a young man who was thirsty for programming. He must have respected how Sirius recognized Bitcoin from the very beginning. I remember that most people were a little doubtful at first, looking at the mailing lists, forums. That wasn't the case with young Sirius.
So, as it appears out, Sirius was registered under the pseudonym "Trickstern" in an old, anarchist forum called "anti-state.com". Oh boy, conspiracy theories on Satoshi's identity will continue.
