Ok that someone would have to firstly keep an eye on the exchance sticky thread, to see if there are any swaps people want to make. Then they would be the one to take down the address of the recipient by PM, and the address of the middleman if there is one. That way no-one's details will go awry, because that person will be trusted to uphold Data Protection laws, which will be included in the rules. I feel quite strongly about there being rules, not only because of policing but also to prevent any arguments- if someone starts for any reason, they will be referred to the rules. So the policing person will uphold the rules and act as peacemaker. Basically as a mod does anyway
Perhaps if people are still worried about that then there should be rules suggestions aswell, so we can compile a rule and guide kind of thing. It's making extra work, but if it will put people's minds at rest then it's worth it
