The wanderers theme

I really would like to see the demo for the wanderers theme but the username demo doesn't appear to be working and does black header in the wanderers them go away? I would not want the users to see the text social template for joomla. Also is there an updated version of the elegant theme or can it work with easysocial 2.x? Does the Echo theme support sidebars on both the left and the right? Can you change the color in any of the themes?
Thanks
