By the way, I advise everyone to investigate the situation before buying any skins. Review the support forums and make sure people are currently receiving what they paid for. Also, assume buying a skin means you are buying it "as is" and there might not be future upgrades because the designer might retire or decide not to renew the site. Save a copy of the zip for your records and so forth.
