A brony from Ponychan is doing a letters from the ponies project, where you write letters, and they write you back! Apparently he is doing a good job of it, and keeping everypony in character, so if you use your imagination it should be fun!
You can find the Google doc of it
here, along with all relevant information on where to send your letters and how to get them featured.
I think Google should start promoting ponies at this point with how much we use their document system.
I'm not sure if this can be considered fanfiction or not, so I'll just roll with it being not fanfiction until someone complains!
Also a
Letters to Rainbow Dash Facebook page!
Here is a copy paste from letter brony!
QUESTIONS=GOOD
HATRED=GOOD

"I'M A SPACE MONSTER GRRR"=BAD
PONY TO PONY=BAD (seriously, I only did it that one time to open up a storyline, and that was before the ED post existed. I might do it once more.)
LOVE=GOOD
LETTERS THAT ARE THE EXACT SAME AS OTHER LETTERS=BAD
LETTERS THAT THROW OUT EXISTING STORY FANON=BAD
HISTORY=GOOD
OVERLY SILLY=DWAYNE
Sadly they are not the true show accurate toys most of us seek! At least Hasbro's marketing department knows about us now though, so maybe something will be on the horizon? 
Artist Training Grounds, I should have banned Pinkie Pie edition. I think in a week or so I might experiment with disallowing the images that follow too obvious, but now that I've typed that I out it feels too mean. Perhaps an incentive system? You can get bonus points for looking for ways to trot off the beaten path, and then at the end you can trade in your points for... shoot I don't have anything to give away except smiles and hugs. I hope those are good enough! Today's image count: 277 ponies in all!
