In regards to the pm I received from coinman,I don't think it's wise to charge interest for the amount owed.People make mistakes and if you don't give them an opportunity to grow,they will never change.Forgive him and move on.
@Mixan : If you're paying him just in hopes to get your negatives cleared,I'm afraid DTS will encourage that.Negatives will still stay as a warning for your shady behaviour in the past.Paying your debts just to have them removed is equally worse.
Thanks for your reply
Actually its not about only mistake its about he really tried hard to ruin my reputation and I am OK if he just stay away from our forum and don't ever try to scam us again
