here is a link to the empty VB plugin i referenced above.
I was not able to find the empty c# one, I probibly lost it or morphed it into a hlf finished plugin
speaking of which
here is a link to the source for the skin switcher plugin i started before it was discovered that the SDK did not support switching skins with CF running. If i remember correctly it accesses the config xml file for centrafuse that contains the name of the active skin and changes it to the one you want, but you have to reboot CF to actually get the new skin, If David can add the ability to the SDK then you would just have to modify this to do it. It two was built for CF 1.5 so it would probibly have to be modified for 1.6 as well, refer to davids API documentation for that. (I dont think i got really far with GUI on this one, I put it on hold waiting for the change to the sdk)
