I moved Stumpy's reply here.... there's no need to start the same thread on 2 boards, and this is the right place for it.
Actually, there's quite a lot of skinning info in the Help files. There is no 'tutorial' for skinning SysMetrix..... you have to figure it out the same way everyone one else does, by examining and tweaking existing skins.
Ask specific questions, and we can help you...
