OP, this is a valid thread and you shouldn't ever hesitate about asking questions on SDN. To this guy^, it's overwhelmingly evident that SDN has tragically devolved into a collection of "omg this has already been asked a million times so go away or search or...just plain leave." With the mission of eliminating redundancy posed ostensibly as your purpose, do you find it hypocritical at all to consistently retort with "this has already been covered"? I would argue that THIS response has, too, been covered countless times. So how about this: if you think the posted question has already been covered, maybe, just maybe, choose not to respond to it. Who's forcing you to reply? Who made it your paralyzingly painful prerogative to just HAVE to respond to all redundant posts? Lay off. SDN is rapdily crumbling at the hands of members refusing to contribute anything significant to this forum. There's a lot more I could say, but I'll hold off - at the expense of being redundant.
