A reputation system is essential to making a forum like this work successfully, I have looked but didn't see anything for rep available.
For God's sake, we dont need another DefaultTrust here.

A would support a trust system here because something is needed when we also have a marketplace board but i would not like to see a default trust system, it's far to open to abuse.
Trust really shouldn't mean a whole lot when trading because you should always use escrow and never trust someone you don't know.
Maybe a trust rating based on amount of BTC risked or trusted with, this can be proven with blockchain links and a trust score worked out.
This was just off the top of my head so it may have flaws i haven't seen yet, point them out if it does.
