.Map :: MoHAA Mapping

Hey what is the easyest way to modify or create new spawn points on an existing map, is it possible for me to add extra spawn script line into an existing .scr file instead of doing it in the bsp?

Hi is there a way to adjust the weather.scr thunder sound so its not so loud,,interesting thing is Its twice as loud when i upload it to a server as when im testing it out on my pc???
