To many people have been getting scammed. There is a solution to fix this! We need /trade. So you can type /trade [username] and put the item in the inventory that pops up. Once both of the traders have put the items, they press Confirm. This way, there will be a lot less scam. ;)
I believe there are issues within this plug-in that allow people to duplicate items. However, if we can prevent this, I totally support adding this command.
Support, I've seen other servers have a way not to duplicate so if we can find out how to do that then it would be awesome!
^ Yeah, I've heard this somewhere as well. My stance is the same as hers; as long as there's no duplicating, support. I'd personally love to see this added.
