I have updated rules for Binges and Samplers and added a new challenge - Big Bites. See
here A Big Bite is like a mini-Binge. You use a portion of the flavor rather than the whole flavor in a similar format.
Samplers and Bites may be used towards flavor completion. I figure, as you're addressing each prompt individually anyway, what difference does it make if you post them separately or as a montage? If you've already posted a Sampler (and I don't think anyone has) you may count the prompts in it on your flavor lists.
