Hello, and welcome to Wikipedia. I noticed that you made a change to an article, Dave Valentine, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you!

Please do not remove content or templates from pages on Wikipedia, as you did to Sport in Australia, without giving a valid reason for the removal in the edit summary. Your content removal does not appear to be constructive and has been reverted. If you only meant to make a test edit, please use the sandbox for that. Thank you.
