Happiness question

[Dubrok]

hi,

i (unfortunately?) made me a race that is "bloodthirsty" (not "peaceful") concerning the happiness type.
i looked into the happiness.txt and i saw that i will have a hard time in a pbw game :-)

now my question concerning treaties: do they affect the happiness just once(when treaty is accepted), or every turn?

and what is the starting happiness number? 0? or -100? what kind of scale is used with happiness?

are troops the best way to keep happiness high? i hope that "troops on planet = -2" means -2 PER troop, not -2 with all troops

thanx for answering my newbie questions.
