I hate to use my first post with a stupid question, but I have read so much my eyes are about to bleed. I was in the process of purchasing service, just a month to check it out... anyways... At the purchase screen, it says mac (optional). Being as I have never did this, do they assign me a specific mac address if leave this blank? Also awesome forum, really knowledgeable people on here. Have learned allot in my reading frenzy. Thanks in advance for the help and apologies for the dumb question, I am sure has been asked a hundred times.
