an Example to make it easier for all..
Remember to write date and Time.. and would be best if you wrote when it ends but it is usual 19:15 to 22:30 longer if players can stay ofc.
Then try to take the ones that signed first.. but if you got like 4 hunters signing first ofc max 2 of them can go, unless you cant make a group without using all 4 hunters.
