I grant trust to molecular with 100 usd, but I have only 0.5 in my ripple acc now 
You sure you want to do that? That means that if you ever hold USD in the system, molecular or someone else can take them from you and in exchange give you molecular IOUs, which he is under no obligation to honor.hey man, are you questioning my integrity?!?
^ this was clearly a joke for those who didn't get it.
On the one hand I feel honored, on the other a bit uncomfortable having so many people extend such hight trust to me.
If I sum it up, I can see people currently trust me with:
- EUR 15
- USD 142
- BTC 8.55
This is beta phase of the software. I will definitely honor any legitimate IOUs people have with me. However it's theoretically possible that something goes wrong and all of the sudden there are some faulty IOUs with my name on them out there. That could theoretically result in some uncomfortable situations having to be resolved.
So please: lower your trust in me to values you can afford to lose (play money!) until we're out of beta.
The majority of people have reasonable values. But 2 or 3 people make up the bulk of above trust.
