Since i was the OP, I guess I'll toss out my 2 cents to all the questions and stuff below..
For the most part.. I believe we were all waiting on the bottle orders to arrive (THANK YOU SARAH!!) so that we could participate. Therefore, the
thread was stalled and just idling.
As to the purpose: I suppose it's two-fold.. requesting samples of flavors you may not have ordered, or if you need that ONE missing ingredient to complete the recipe you saw on such-and-such a
thread... AND.. even doing swaps if there are several flavors you'd like to try, perhaps then you would like to offer a trade.
Whatever we end up doing, I don't think anything is set in gold. It was more of a 'why don't we try this?' kind of
thread.

So there are no set rules.. it's whatever we make of it. (I do think a PIF type set-up is a duplicate of the DIY PIF thread, unless it's an occasional offering, I don't see basing the entire thread on that format) But I'm open for anything!
