These options are set from the Skins tab of the Appearance Manager interface. These functions allow you to work with skins that are already installed on your server, including those skins that came with Discus and those you might have installed yourself from other sources.

If you know that you will never use a particular skin, to remove it from the server, click the delete (trash can) icon next to the skin to remove. Or, mark boxes next to all skins you want to remove and then click the delete icon in the bottom row. Note that you cannot choose to uninstall the skin you are currently using for your board.

Deleting the skin removes the skin file and any associated icons from your board. Each skin you remove will generally save between 50 and 150 kB, depending on the size of the skin file and the number of icons associated with that skin.
