SDCC Flyer

A flyer was uploaded to Dulfy.net on Friday July 25, 2014.

However a different version, with the letters REN underlined, was uploaded on Sunday July 27, 2014.

Speculation
it is speculated that the underlined letters are part of one of the previous codes, or it may be its own code or key. It still remains to be see what can be made of those letters.
