I've done a lot of editing of my forum skin in the control panel. I want to make a copy of the skin that I can work with and view quietly, without messing up the skin the community sees. Is there a way to copy my customized skin so I can do this?

You can do this by exporting the skin and then importing it.

You can also just create a new skin off that shin and only give yourself the permission to see it.
