I experienced this while having a TWC myself. As anyone who has a TWC knows, getting a deal done without a middleman is tough to do, especially if it is a larger one. Middlemen are imperative to the trading process.Why would you discourage safe trading practices by disallowing TWC users to have access to the best, most qualified middlemen? I think (unless it's something to difficult to grant in terms of development time) twc users should be given access to the VMM forums. There aren't any massive drawbacks that I can think of.
