Bukkit

If you have an effect applied (for example, speed) and you join the lobby (/pb join) those effects are removed from the players. But could you add an option to not remove those effects?
For example, in the config.yml:
remove-effects-from-players: true/false

If I add something for this in the future, I would prefer a setting which defines the effects which are active in the lobby, instead of keeping the player's previous effects.
