Yezhead- if it's not too late to answer you, sometimes people cover with cheesecloth for a few days to allow the good bacterias to get into the peppers and start fermenting but then it needs to be covered to keep the oxygen out and allow the CO to fill the jar. I'm not a fermenting expert, but I'd suggest using some kind of a starter with previously frozen peppers (kefir, whey, or others as suggested in the Fermenting 101 thread)
~guru- the seeds and stuff can change color and look funky from freezing. As long as you know they froze quickly and safely, they should be safe to use, either to dehydrate, ferment or make a sauce. It's your personal preference whether to pick out the discolored seeds or leave them in.
