This is the last line in each email that Feedburner sends out when you subscribe to a feed via email.  Sounds like a joke- but I think they are serious. I have Feedburner send me my posts so I can get to them from Gmail and also so I have an archive of them (which, for some reason, is reassuring). But anyway, at the end of every email they say how you can subscribe via RSS "if your inbox is too full" or you can unsubscribe with a link, but then they throw in the postal mail thing, pretty weird. I may try it, just for kicks. I wonder what the turn around time is...
