I haven't read it yet, are you POSITIVE it said not to prime...or not to add more yeast???
I can understand them saying no more yeast is necessary, but not priming...though thereotically and even confirmed by running numbers in beersmith, a beer can be carbed without adding any more sugar, but it would take a long time for the co2 to max the headspace and then re-absorb into the solution. Hmmm maybe that is where they are coming from...if you are bottle conditioning for a year or more, maybe they figure you don't need the extra sugar...
