Sorry for the double post but my quick link to LVL goes right to the forums & I didn't see your more extensive info about it on the home page. And I am not sure what you mean by the "freebie recipes"; can you elaborate more about this? Thanks.
No worries at all!
Back when it was actually Nik Software (and not Google) that owned the plugins, they had free recipes available for download... Basically, presets that were user-contributed or just extras that weren't included with the official software. You can install them for additional looks in Silver Efex Pro and Color Efex Pro.
There were 90 altogether, and you can download them individually or in total.
