Rejecta Mathematica

A reader emailed me about a new online mathematics journal, Rejecta Mathematica. As far as I can tell from reading the FAQ, they only publish articles that have been rejected by peer reviewed journals. The twist is that with your submission, you must include a letter that describes the reasons the paper was rejected as well as any other flaws the paper might have. Submissions are not peer reviewed, and results are not required to be either correct or new, but submissions can be rejected, if they are deemed either incomprehensible or not mathematical.
