I rolled a -2 Int mod on a level 1 fighter today and if i'm not mistaken that leaves me with 0 starting skill ranks, correct?
From the Pathfinder SRD:
You apply your character's Intelligence modifier to:
The number of skill points gained each level, though your character always gets at least 1 skill point per level.
Emphasis mine. Your level one fighter therefore has one skill point. Spend it wisely!
