You never hear anything from most open shows but if the payments come out of your account then your entries have been recived.
Some people will get proof of posting the entry forms as if you can prove that you posted the entry then they will have to accept it. So you might want to do this in the future if you can get to your post office to post each entry.
Personally we just send them off and then turn up at the show, never had a problem.
