I suggest implementing a new role (that people can gain through a react message) where it pings them every time the middleman queue is open for use. The role would be @'d in the normal "The MM queue is now open" message.
A complaint that I've seen sometimes from people who are suggested to use the middleman queue for future trades due so some kind of past complication (typically a scam) is that they don't have the time to continuously watch the channel to see when it's open or it's simply too cumbersome to try to stay on top of when the queue is open or closed. Although I'm personally not someone who would want to use the queue (I just don't normally do trades), I imagine it would make things easier for the people who do want to use the queue, with minimal effort from the Middlemen themselves. If I'm wrong in thinking so, please let me know
