Just a note to all:
The respawnType "Side" or "5" does not work, and merely reverts to "Group".
If using respawnType "Group" then respawnDelay does not work.
davidoffo, to answer your question about respawnType "Base", you need to read the wiki entry for "description.ext". In there it mentions that you need to create a marker on the map for your corresponding side. The location of that marker is where you will respawn.
