Table of Contents
This is just a bunch of my random notes while problem solving. It may not be of any significance, or it may be vitally important and I'm just a tard that doesn't see the obvious. My notes are here, in case they may spark off somebody else's thoughts.
The file alison.rtf contains the string of characters 2oc4o:ptxt. It is interesting to note that both the filename and contents are the same length. Furthermore, an IRC chat mentioned that the previous value (2oc3o) was incorrect. This seems to indicate the value itself is important: "2oc3o" by itself had to be corrected. If it was simply a directory or file name, a correction might not be necessary because the directory or file could be renamed. The fact that it had to be changed implies that this value likely interacts with something else.
I tried to perform a few mathematical calculations (converting each letter/number/symbol to a number first).

What about a custom A-Z0-9 alphabet instead of the ASCII table ?
Problem: what to do with punctuation?
This time, in decimal, using the following table (instead of ASCII):
