Did you type a connection that was correct but not get the points you deserved? If so, sorry. The system isn't perfect. Do give yourself the extra points mentally. (There's probably no need to comment about this, unless it's constructive.)
PF: Not an unique solution.
You can be 'Saving Time' and 'Money' is a Pink Floyd song, so both can be interchanged. (6 months, 4 weeks ago)
BSD: Ridiculous! A good grid requires skill, not bizarre niche knowledge (7 months, 1 week ago)
ScarletFish: No idea what BSD is! Guessed “Computer Systems”, so not a million miles off!
Also recognised Echoes as Pink Floyd, so tried Albums (but not PF)
Some good red herrings! (7 months, 1 week ago)
a: spacegroup: they're also all potentially infinite, or indefinitely great in quantity (7 months, 1 week ago)
