Does anyone know a good place to post a ff about Snape with an OC? I haven't written it yet but if I could find a place to post one, I could finally get a start on my idea! lol

u may use FanFiction.net. It's easy to use.

Wherever u post, please put a link here so that we may go and read it, okay ?

(A small piece of advice from one fanfic writer to another : start your story, no matter what. Don't post it right after starting, because if u need to change the plot, it's meer difficult to change. Once u have completed about 80% of your story, then u can post. So u have time to look for a place to post, don't worry !)

sycophanthex.com has a Snape/OC category in their Occlumency archive, where I'm currently posting mine. I think it's a great site and hosts lots of different Snape fanfic.

I post mine on fanfiction.net, Occlumency and The Petulant Poetess

Fanfiction.net is a good place for all sorts of fanfics. good luck!
