how to use GTK-Gnome themes

Extract the archive then put Nova-Lime, Nova-Gold and Nova-Blue in your .themes folder in your home directory.

For a quick drag and dropless installation, type this in the terminal in the directory of Nova.tar.gz.
tar -xf Nova.tar.gz
cp -r Nova/* ~/.themes
Then open your Gnome theme control panel (assuming you are using Gnome), hit properties, and change your "Controls" theme. Also, make sure you have the Mist engine installed for that theme, if you don't it will not look right.

Based on his previous topics I'm thinking he runs Windows and doesn't realize those themes are for Linux? If he dual booted you'd think he'd know how to use the themes.

Just a wild guess though... an assumption really.
