There are only a handful of themes on the site here that actually work. There's an error which causes the theme to not be shown -- I am currently investigating this. Until this is corrected, please only use the default theme. I will keep you posted if I have any more updates. The default actually looks pretty nice and you can choose between blue, green, and red for the colors.

I'm still getting used to the new version of php fusion here so sorry if updates are little slow. :)
