Just to let you know, Vader is the past has said sometimes he does not respond to posts directed towards him, he prefers it thru PM.

 

yep it's always a bad idea to ask for someone by name when all you want is help with a problem. there's always half a chance mark or me could of answered your question, but since we ain't vader we never bothered.

 

Maybe 1/2 chance with you, only about 1/10th chance of me answering it.
