**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).
