Since there are a lot of power users here that know what's available I never know if it's worth submitting utilities or not but I will in the event it might be useful. This little utility converts PS palettes and Kuler palettes to Gimp palettes. I've found it useful in the past, maybe somjeone else might. Sorry if everybody knows about it already. It's called Palette Parser, http://www.webbiscuit.co.uk/PaletteParser.aspx
