A notify or announcement feature and many more

I like how this web works but if they add a feature where by if u are offling but u are still connected to the internet u will recieve a notification of someone accepting your request and also announcing to people about other trade request if the one requesting and the one accepting is online and you guys should have at least two private severs for trading and also a premium pack for people like for their trade to always be at the top and giving them the best trade option and an advance security check
