Game and Team Pickups
If a team has less than 6 players show up for a game they can pickup anyone wanting to play to bring their roster to 6. I don't want to worry about forfeits and it's impossible to keep track of who's on the spares list.
Adding and removing players from your roster throughout the year is fine as well. Injuries and other factors come up and it should be the teams decision to add or remove players.
The exception to both of these is playoffs where your roster is final and pickups must be agreed on by both teams.
