ACDSee pro 6 question.

i have had the ACDSee pro 6 processing system on trial for about three weeks.

i quite like it as its not silly money and it seems to be a more able system than the nikon view nx2 i have been using.

can i get any black & white plug ins to suit this system so i an maybe try different things in time with my images, im thinking about something similar to silver efex or thereabouts.

also if anyone uses ACDSee pro 6, can they tell me how to save as a RAW once the RAW image has been played with, i cant see that i can do this, but i can on nikon view nx2.
