This plugin enables you to restrict the amount of allowed deaths per player. Each player has an initial amount of lives which is decreased whenever the player dies. When a player runs out of lives, he won't be able to join your server anymore. A possibility to gain additional lives could be to vote. You can configure commands being executed on every vote in GAL.
All messages are configurable.
