I have been doing some messaging about doing some trades and come across things that I do not understand.
I get a match alert for a card and it does not show up in the shreach of my want list and his for trade/sell sort.
Cards on my want list and his for trade/sell list does not get a match alert.
Cards on the match alert but the guy does not have a for trade/sell collection or even a send message button.
Card in my for trade/sell sort still shows but I have removed them over a week ago.
It appears to me that the match alerts are just the new ones for that day and that person.
