Thanks for your efforts to improve the English Wikipedia. I wanted to let you know that edit summaries are for briefly explaining what change you're making to an article or why you're making such a change, while urls for the sources of information you're adding should be added directly to the articles themselves as part of inline citations (not to the edit summary). You're not expected to know all of that immediately, and it's great that you're using edit summaries and adding sourced content. Please do take a few minutes to read the two pages I linked above. I'd be happy to answer any questions you may have, or you can ask at the help desk. Rivertorch (talk) 05:20, 8 August 2012 (UTC)[reply]
