Welcome, fillies, gentlecolts, and bronies everywhere to Pony Draft, the website where fans of My Little Pony: Friendship is Magic can share their awesome works of fan fiction before they are complete. These fan fic "drafts" are then open to praise, proofreading, and constructive criticism to help improve both the story, as well as the writer's skills.
Once the writer has received this feedback and proofreading and subsequently improved upon their story, I recommend sending them to Equestria Daily, which does state "As always, please proofread/have somepony proofread it for you before sending it." or else Sethisto and his pre readers will more often then not "send it to the moon," so to speak.
So go ahead and send in your incomplete or unedited pony related fan fic/fan fic chapters, and get some feedback before calling it a finished product. It truly is amazing how many things can be spotted and improved just by having somepony (hopefully many) look it over. For submission guidelines, check out the "Submit" page.
If you have any additional questions, comments, or concerns feel free to talk to either myself (Enigma9994) or my trusty editor Master Shake, through either the comments section or through email. My email is firstname.lastname@example.org, and Master Shake's is email@example.com.
