I like this idea for a #LettersToTheEditor #preprint server.

"Such a preprint server would offer three major benefits…: format-free ease of swift communication, increased author visibility and accountability, and avoiding the homelessness of unpublished [letters]."
PS: I've sent letters to journals that had policies not to publish them, but without saying so anywhere. Once I sent a letter to a new journal that had never received or published one and needed time to think about it. Right now #SocialMedia takes up this slack and does a pretty good job. But posting letters as preprints would give authors more space, prevent even published letters from languishing behind #paywalls, and offer better opportunities for #PIDs, #metadata, and #discoverability.
