just noticed that you're creating a sandbox to work on the unconventional oil article i'll keep an eye on it and see if i can help i don't know whether your course suggested you use a sandbox but you could actually just edit the article directly instead if you like that's how wikipedia works there's no need to prepare stuff in a sandbox first but it's completely up to you and what you feel comfortable with i'll also watch your talk page so if you do want to ask anything you can post here or on my talk page talk
