Exhausted is a two-column, widget-ready, WordPress theme with a semi-calming color scheme.
Web 2.0 is a widget ready, two column, fluid, modern looking theme for WordPress. The colors for the theme were inspired by the Web 2.0 colors.
I have used wp-manage and found it can handle only single installation, not good when need to manage multiple blogs, so I use wp-managedx2. Much easier and saves lots of installation time.
