As they put it:

[T]he deadline for submissions to the next issue of Protodimension is Sunday, January 5th 2014. We are as usual looking for horror-conspiracy-weird genre gaming stuff so please let us know if you have anything you would be willing to share with us and our readership. As a freebie mag reliant on fan contributed material we can’t pay you, but I hope that doesn’t put everyone off! We have just added the excellent “Achtung:Cthulhu” to the list of games we support too, thanks to Chris Birch of Modiphius, so there’s another RPG for you to consider!

While I have not been a regular reader of Protodimension, they did serve as an inspiration for the Arkham Gazette.  I figure we tiny gaming ‘zines should stick together, so if that sort of thing is of interest, take a look.
