Hi LoyceV.
After rereading the thread, this time all the pages, I have a couple of questions.
A) As for leaving feedback, I understand that it is mainly to be used if 1)you have traded with someone or 2) if you would trust someone to trade, even if you have not traded yet. This second part is more subjective and can be based on his behavior in the forum. 1) is straightforward, for example, you can leave a feedback: "I traded 0,1 BTC for x Eth, trade went smoothly".
But don't you think that leaving feedback because you would hypothetically trust to make a trade with someone (2) is more subjective and may result in people leaving feedback simply because they like the other person, for example? (Although if they like the other person, it is normal that they would trust him to make at least some small deal but I hope you get the idea).
seems to me that I will have to rethink and maybe delete or modify some feedbacks I had left.
2) As for building the trust list, how do you do it? I mean, I think it's clear what needs to be done, but how often do you add or remove people? Do you do it as it comes? If you see someone leave feedback that catches your attention, you go and look at their trust list and then decide whether to include or exclude them from yours?
