I didn't get any mail about my submission. Does that mean it was rejected? It said 64/100 (I haven't participated in too many HHs, so I don't know if I read it correctly) vouchers left when I submitted my post. I checked the IndiStatus page and couldn't find the status of The Great Indian Litterbug either...?
If your post is rejected, you get a mail informing you about it. If it is not among the first 100, you may or may not get a mail about it...
