From what I understand, you likely created a topic within the Listing Discussion of a Looking for Group Listing (LFG Listing). When someone replied to your topic, you recieved a reply notification, which you accidentally dismissed. Now, you have no way of finding that topic again. Notifications, once dismissed, are gone permanently. You will have to find the reply to your topic another way. In order to find the topic that you posted, you must first find the LFG Listing that you posted that topic within. You should be able to find that LFG Listing through the LFG Search Tool . Regardless, it is best practice to use a browser bookmark ( Browser-Lesezeichen ) to bookmark LFG Listings in the future so that this does not happen.
