Welcome!

The main wiki for Creepypastas is The Creepypasta Wiki. They are quite strict about what stories they accept, although they do have a Writer's Workshop for help and advice for beginners.

There's also Freepasta Wiki, which is like Creepypasta Wiki but less strict. That's inactive at the moment.

Or you could use a general fiction wiki like I Love Writing Wiki to practice your writing.

Good luck!
