What platform/site do you use to upload your scripts?

When I write my scripts I write them in Word and have my own writing style that works for me. But when I try to copy and paste that to reddit or scriptbin it disregards the format. Then I have to go back and re-bold things and just re-format the whole thing which takes some times when it comes to longer scripts.

I was wondering if there was a site or something that lets me upload my scripts and make them viewable as a PDF?
