It's to indicate that you are a premium member and it's a lot of trouble for Smart Matches if it isn't there. I've even made a post before about how important it is. If you mean that they should just change it to a different icon than the crown then I'm with you, but not to get rid of it completely.
Thanks for the info. I do know the importance of the icon, but I don't like to wear a crown and be a king and get all the attention on me. There should be other options of selecting an icon from a list or simly to show that I'm the Administrator or The Webmaster of my site and other members on the site who I promote to as Site managers to appear as Site Managers only.
