Hi
Just thought I'd point out I've launched http://www.roundcubethemesandskins.net as a attractive selling tool for the mVision products. Remember mVision has a 3 pane layout which includes vertical mode, something no other skin has. Cross browser, including IE6. Supports mobile too.
Also see http://blog.roundcubethemesandskins.com for free versions of the theme and other free downloads.
