Hello, Khristine16. Welcome to Wikipedia.
I am FlightTime, I am a volunteer with the Account Creation Team and I received your account request. I'd like to welcome you to Wikipedia. Here are some useful links and information to help you get started. You are welcome to leave questions, comments on my talk page at anytime here.
You can create your own "Test" page by clicking on this link > User:Khristine16/test < This will open an edit window on a page with that title, add something in the edit window and scroll down and click the Save page button and you've just created your first page.
Edit existing articles, before you make your own. Look at some subjects that you know about, and see if you can make them a bit better.
When you're ready, read about Your first article. It should be about something well-known, and it will need references.
