Went over to the plugin's site but could not understand any of the language. Sorry.
Has anyone used this? How is it installed? Would that be in the mu-plugins folder? How is it customised?
Can it be used for multisites with around 400 blogs? Will it "kill" the database?
Any bugs? If any found would the author look into them? Will this plugin evolve?
I know. I know. So many questions....
