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
