My first thread was inadvertantly deleted so I'll try again for some assistance.
This is my first year refereeing, I've worked four matches, one as up ref.
Tomorrow I'm scheduled to do a JV or MS (can't tell from the schedule which) match solo, with no follow on game so no one else will be coming or watching.
Anyone have any tips for how I should handle subs and talk to the scorekeepers? Any help would be greatly appreciated!
