Nice little math trick there xDDD Love it. (Just a hint for you oblivious or math retarded people out there, if you mulitiply anything by nine, the digits will ad up to nine. Multiplying by 3 twice is the same thing. So. :P)
I think I should clarify why? Been following for a while, just prefer to understand what is and is not acceptable before I even attempt to submit anything. Gotta have a feel for a place/people and that does not happen going to a site once or twice.
