I came up with this idea in another forum that I usually hang-out into (A KARA fanbase forum) and they have this marketplace forum where they post KARA-related items and sell it to other members. I wonder if this kind of forum would be also be applicable here. I don't know if there are indeed SCANDAL merch sellers/buyers here tho.

I know this might be a difficult one to handle but I think the one that is accountable are those who made the trading -- not the staff.

Not allowed if I understand your post correctly :

Rules-sama wrote:16. Selling of any item including SCANDAL stuffs are not allowed. This is a forum of appreciation and not business. No member is allowed to profit inside the forum. Proceed to other places if you wish to sell and make money.

.omg.  How did I forgot that rule? 
Sorry.

Please disregard this suggestion.  .sweat.

We discussed this in the past before we updated the rules and we just didnt want to have people leave the forum because they had a bad experience with a seller. if someone were to be scammed or something of the like they would most likely not come back as they would associate the forum with that bad experience. We just wanted to avoid all that and have a good time

I get it. Maybe the time you guys were talking about that, I was away -- busy with school. haha.
Too many things happened when I was away.
