hello gents long time no see. I've found that when low on combat caps, say 2, and we have rokhs (cap hungry blastards) in the fleet, and I saw multiple nighmares constantly broadcasting for cap, that as an FC-t if I asked for a nightmare with a cap transfer to X up in fleet, someone would, and I would "By the power vested in me by by WTM congratulate the repeated broadcaster and suck-- volunteer on being happliy paired as a cap couple."
It sorted the problem quickly and people got the idea that if they asked for a cap buddy the FC would take the initiative to "gently encourage" someone to help their fellow pointy vertical supremacy battleship out if no one volunteered.
