Being lazy, I've simply included the paragraph:
Actually, that's not true, a score of 0 will still keep Eve on the list, only a negative score, i.e. more people distrusting Eve than trusting her will lead to her exclusion.
I'll leave the example with only two lists standing for simplicity's sake, though.

It would kind of defeat the purpose of my "short" introduction to the Trust System if I were to explain every little detail.

The final Trust List that the forum's software will generate will now look like this:
* DefaultTrust
* Alice
* Bob
* Carol
* Dan
* Frank
* Grace
* Eve

Those are the people whose judgment you trust for the moment.
All Feedback left by those users will be taken into account to calculate the Trust Score you'll see displayed.
Of course, your own Feedback will be taken into account as well.

You might have noticed that Eve doesn't show up still shows up in the final list.
The reason is simply that Eve is added "positively" to the Trust List of Alice, but at the same time, by the prefix "~", Bob tells us that he explicitly distrusts the judgment of Eve.
The software will now calculate "+ Eve" and "- Eve", which equals "Zero Eve", so Eve won't show up. To remove Eve, someone else has to add "- Eve" too.
Actually, that's not true, a score of 0 will still keep Eve on the list, only a negative score, i.e. more people distrusting Eve than trusting her will lead to her exclusion.
