There is a new forum if you want to request a middleman or mediator for a trade. It can be found here: http://www.ko4life.com/forums/index.php?showforum=71 (it is the first forum in the "Market Place").
Mediators are either ADMINISTRATORS, MODERATORS, or TRUSTED TRADE MEDIATORS. Do not accept mediations from ANYBODY ELSE.
We hope this sorts out the trade mediator issue.
