Just so I have this clear in my mind, at the end of March if anyone remains ungifted, Goodbye and Good Riddance would remain open for another month for the round of pinch-gifting (which would go on until the end of April?)
I like this. I think the threat of thread closing on 3/31 will be a bigger spur to people than a less formal "get your pinch hit requests in now" process a few weeks earlier, and keeping the thread for one more month wouldn't be too onerous. (And if a month isn't long enough to get your pinch hit gift out, don't volunteer.)
