WPMU DEV Random Theme on Signup 1.0.1

Description

Random Theme activates a random theme for new sites or blogs on your Multisite network.

Rather than seeing the same old default theme on every new site, users get a much fresher experience.

Installation is simple, just activate the plugin from the WPMU DEV Dashboard and then network enable the themes you want to use.

After that, new users who create sites will be allocated a random theme.
