There are several requests for new features to improve the matching system.
The report Items on your Wantlist that match items on other members' For Sale / Trade lists use to show only the sets that had matches for you but due to an update things were changed. Now it shows all sets that are on your want list . Then you click on that set and it informs you that there is no matches. Admin told me he would try to get to back to what it was but may take some time.
Last Oct I made a list of all the matches for cards I need 97 total. Out of the 97 there was 54 of them the members were not active. 8 offfers were made and with drawn because of no replies. 10 members were only selling. (way to high for me) 2 members I could not work out a trade with. I send messages (several each) to 15 members No replies. That left only 8 other trades that worked out. I'm really thankful that more members have added a lot more cards that I need so I can keep trading here.
Yes it was a lot of work and have not done it again.
