At RuneWish we do not use a middleman rank. Instead we have a Verified Merchant and Merchant. Users who have the merchant badge are users who trade a fair amount and understand how trading works. This badge gives them a bit of extra trust in the black market. Users who have the Verified Merchant badges are highly trusted users that have conducted many transactions valuing very high in wealth. Not many people will have what it takes for the badge and this makes them as trusted as it gets without being staff.
ONLY Verified Merchants, Moderators, and Admins CAN MIDDLEMAN TRADES AT RUNEWISH
You can not middleman if you do not have one of those badges.
-These are the middleman limits-
* Verified Merchants | Max Middleman Value: 200m (Can ask moderator or admin permission if they want it raised for higher trades)
* Moderators | Max Middleman Value: 1000m (1b) | (They can ask admins for more and usually will be allowed to)
* Admins | Max Middleman Value: Unlimited | (Can middleman any and all transactions)
