I've attached a screenshot, i can't find the place where I am supposed to do the trading from to get the items from the portal, unless if i am missing something?

I checked the logs, the trade quest for today was already completed by another player. So everything is working properly but you got to the portal a bit late.  Sorry for the confusion.

So how long do I have to wait? About how many hours before I can do the trade?

Please check the news thread. There's one trade per day.

aww okay, so i guess i'd have to perhaps ask the next person who gets the portal to lend a hand in maybe helping me with the items I suppose...guess i didn't make it in time...and I don't want to claim portal for that long either, so yeah, i'd have to ask next person...I wonder, do these new item comes in as a scheme? or item...item?
