I have several Microsoft Windows systems (as well as Linux systems, tablets, etc -- I'm a s/w developer...)

Do you sell a site license for MM? I have several systems running the free version, but I'd like to upgrade at least a couple of them to gold - perpetual, of course. Do you have a site license option, or a multiple system discount?

Thanks!
