I wasn't sure if you mean your application was not processed or if you are unsure if you were picked as the owner for a fanlisting, so I've gone ahead and answered both.
Please remember that it sometimes takes a few weeks for received applications to be processed (and if it is a subject from a new series those applications may be held for awhile to make sure people are given time to apply). If a full update has been made in a certain category and you do not believe your application was included (make sure you check the blog to make sure a full update has taken place) then you can ask if your form was received in the appropriate category forum (each sub forum has a thread for checking on forms). You can also send in a contact form to the specific category staffer, but most often you'll get a quicker response if you post in the forum.
If you mean that the subject you applied for is on upcoming but you don't know if you were picked as the new owner, you can have
your fanlistings list sent to you or you can check in the appropriate category forum. Also check your spam folder, as sometimes TAFL emails can end up there.
