Didn't look it Pern although I only had a quick look. Do you have a copy of the skin you like in your skins? If you do just copy it and apply it to your other. The individual boxes just click edit and highlight the lot then switch IDs and open the equivalent box, delete what's there, save it empty, then reopen and paste in what you copied across.

I didn't notice how many boxes you're using but it shouldn't take long even with them all full and I doubt they were.

The alternative is to just copy the source code from the profile you like into notepad and use that on your other ID.
