Op I'm not quite clear with the project you are trying bro pull up. Are you trying to stand as a mediator to p2p transaction between member of this forum to ensure transparency?
Are you going to be taking commissions from successful trades?
What are the odds that a reputable member's account won't get hacked and used to scam  another person? And if this happens how can it be resolved?

I feel we should also consider questions like this before running into such transactions. I believe this is a public forum and any one can just create account and hunt  merit while he still uses the account for scam, these days scammer are becoming more patient and sacrificial. When talking about any thing that has monetary value experience has taught me to conduct only trusted and physical(knowing each other) business I don't know about the risk tolerance of others but I prefer an anonymous trade with a  trusted user.
