Here's how I think the story unfolded:
There was a special Codebreaker section on the Submerge website that at
first appeared to be nothing but a blank page, but it had a secret link
hidden behind a single dot on the page. The morse code in the track said
"click on the dot", which revealed a page written by the Unknown Writer
about codebreaking and resistance.
A listmember decrypted the code and forwarded it to 313 and everybody
accessed the site. A day later, a message from Submerge appeared on the
site and on 313, saying something along the lines of 'the code had been
broken and the mission compromised' and that the site had been taken down
(although another listmember had saved the page and forwarded it to 313
afterwards).
