And Here Are My Settings For Rankup:
# Remember, YAML does not understand the 'tab' key. You must use spaces instead.
# Note that this plugin REQUIRES you have Vault. Download it here: http://dev.bukkit.org/server-mods/vault/

# If this is true, it will override any groups when someone ranks up. Only worry about this if a given person may have multiple ranks.
