-Also sending a SASE (self addressed stamped envelope) is also recommended, alot of celebs probably won't pay to send it back.
-Sending early is always recommended but NOT to early I would say about a 3-5 days before the production is scheduled to start is a safe bet.
-Don't get discouraged if you have not recieved anything during the production as I have seen many successes even months after the end date. Some celebs play catch up afterwards.
If you have any questions Please don't hesitate to ask admin

Good luck and please don't forget to post the via venue successes or return to senders you get on the 'Via Venue Feedback' Forum.
