Tanelorn,
my reply was to your post long ago , Dec 2011
what I wrote in blue, is crystal clear~!
and only posted my reply to help other newbies as well as yourself.
I dont know what those marks are...one thing I do know they are not Spanish, trees not near old
enough, most likely if not graffitti, then KGC might be an avenue, try posting them on the KGC thread
and see if anyone has any idea.
In general I dont discuss kgc stuff as it is "take off" of the Spanish Code, while I am researching all the time for reliable information about them , I dont want to confuse readers with the two seperate types of Code..I only diagnose Spanish and read and learn what I can about KGC and Yamsheetas code for now.
hope you find some answers
