I don't see why "groups" prop gates open for the rest, then carry on. If you're fit/fast enough to get there first, hold the gate, count your group through, close the gate, then use your god like riding or walking skills to make your way back to the front ready for the next gate.
Way back when, I used to leave them as I found them. Now with so many people in the great outdoors who just don't seem to "get it" (you know, the ones who look miserable as sin), I'm erring on the side of close it anyway.
If there's a blatant sign asking me to close it, it's a no brainer. Most places we ride are actually a workplace for someone else. I hate it when some pillock has been messing about with my work space.
Am I just getting old or are people now incapable of sparing a thought about anyone else at all?
