We think this system works very well, and we know that you will agree. If you want your work to be considered for both the print and web versions of McSweeney's, please indicate this at the beginning of your email message. Under no circumstances should you send your submission in a way that requires a signature. Any submission sent this way will be thrown out, then burned at dawn, the flames from which we will dance around with great joy. We are very serious about this.
Regular mail is fine.
Do not FedEx, UPS, certified mail or Priority Mail your submission.
