[Spooks] Numbers Tutorial

[Ary Boender]

Thanks for the tutorial, Mark. I'll put it in N&O this month together with the
M8 one.

>the past intercepts for M13 on the Spooks Database and the Enigma Database
>on Ary Boender's "Numbers and Oddities" site.  

Please note that the database on the N&O website is not the Enigma database but
a database that contains Spooks logs + WUN logs + logs sent directly to me.

Cheers,

Ary
