Dandu, great thinking, though we don't currently run stories. We're really focused on content directly applicable to the game!
RUMBLETiGER, mechanics guides would work fine as long as we include them in a thematically relevant issue; also, we have to make sure and only include either original/homebrew information or information from OGL sources (like the SRD, etc). I didn't have a lot of time to check the sources to which you referenced so I'm not certain whether that was an issue but it's the first thing I thought of upon skimming it.
And yes, xigbar, from outside contributors, we're looking for homebrew content.
