Hi, everyone. It's finally time for me send PA a letter to ask that they not renew my contract, and I'm not sure what address to send it to. They have a PO Box address on their website, but I want to make sure they get it, and I've never had much faith in PO Boxes. Does anyone know their street address? Also, who do I address it to? Just generically "PublishAmerica", or someone specific? And finally, is certified mail or registered mail the way to go? Sorry for all the questions. I've been waiting for my contract to be up for so long now, I don't want to screw anything up
