Maybe the numbers point to certain words in a text. This means 2.4.1 points to "after" and 2.12.8 points to "where". Now we just need to find the
text that was used.
We can also try the IP thing. Maybe the cerberus in 5's post means Kerberos, a network authentication protocal. Cerberus is also a FTP server
program. It's possible the IP is a FTP running Cerberus.
the previous clue to this said find it in talk of three, or words to that effect.
So our text could be related to that.
three's only listed post does not fit the bill.
But there are topics on the rest of this site like " The Three Wise Men " etc.
