i dont see why not to 'ripple-trust' me 
Thanx
Just remember, if you extend $5 in trust to someone, they can wind up owing you $5. If you don't have a settlement agreement with them, that could mean that $5 you intended to be able to spend or cash out is now a worthless IOU. Trust in Ripple is a powerful thing. ThanxAre settlement agreements always negotiated externally, ie. by word of mouth? Or are they written into the public ledger?
