I would like to post an Alicorn OC story, but I really have no clue as to how to go about it, yes, I am still pretty new around here.

4363241 since you just joined, it would be best to hold off on those stories until you get more practice.
I can give you the links to two groups that can help you with your OC
OC Life Stories
OC Edit Group

4363482 I am taking your advice, but in a bit of a different way, realizing how difficult it is to create an Alicorn in anyway, and having it even be remotely acceptable in the fandom, I have decided, my Alicorn OC will remain personal to me, and never see the light of day beyond my own mind, and a few close friends. I do understand being a story teller, is not an easy thing and takes special skills that I may or may not have, I have to accept I am a role player and poet, not a writer or story teller, I thank you though for your advice. maybe though I will do a story someday about my OC Poetry Motion. Mayhaps, I will just continue to be a reader.
