Okay, this is a confusing process at first, but it tends to get easier when you go through it a few times...
Your going to go to My Mibba and scroll down a bit until you see the 'Stories' heading. Under the heading is going to be a link titled stories. Click it, and in bold font, you'll see a title that says 'New Story'. There'll be a link titled 'Add new story'. Click that and it'll take you to this form like thing, that you'll need to fill in order to start your story...
Confusing, I know...
And once your done with that, I'll tell you what to do next....
Lol...
Just kidding...
That'll be great!
I'll definitely read...
