I have over 150 blogs in my network and sometimes I need to put one into maintenance mode to work on it while leaving the other ones active. WPMS Site Maintenance Mode Plugin doesn't work for me because there isn't an option to put individual blogs into maintenance mode.
Does anyone know of any other maintenance mode plugins that will work with WPMS for individual blogs? I've tried searching, installing, testing, failing and uninstalling plugins for the past several days. I'm asking here as a last resort.
