The point of having a language is connecting with others, communicating clearly, and finding common ground--which is why I've never really seen the point of having your own and not sharing its meaning with anyone else. I could understand sharing with a friend or other confidant exclusively, but ... well, it's kinda like comedy, it isn't as fun if you're the only one who gets the joke.
That said, welcome to CYS. Check out the Help & Info section's articles if you haven't already, they're very informative. If you'd like to put your creativity through a vigorous warm-up before starting a story of your own (or just for kicks) I invite you to join the writing exercises I'm hosting in the writing workshop. PM me if you'd like to be added to the tag and scoring list to complete exercises in a timely manner and earn CYS points, but otherwise, people are free to post whenever.
