I have noticed something in other MMORPGS that Istaria does not do immediately, but until a player presses a button:
the Trade Window.
Can there be a way, that if you initiate a trade with someone, the window pops up on both clients, to let the other player know they are being traded with? Or maybe just a requester "<character> wishes to trade with you <accept> <decline>"
The way it is now, you have to initiate a trade with a player, drop the items into the window or send coins, and press "Accept" button. Only then does the interface appear on the other player's screen.
Many times, the player runs out of the trade distance range and the trade fails until the two are close together again.
Even if you say "I have a few extra pots you can have" it gets lost in the sea of chatting, and the person runs away from you, not knowing you have started a trade with him/her.
