Thank you for your contributions to Wikipedia. Before saving your changes to an article, please provide an edit summary, which you forgot to do before saving your recent edit to Ming Dynasty. Doing so helps everyone understand the intention of your edit (and prevents legitimate edits from being mistaken for vandalism). It is also helpful to users reading the edit history of the page. Thank you. Please note that you will probably have your edits reverted if you don't use edit summaries. I'd also like you to respond to this to show that you are going to work with other editors. If you don't you will probably get blocked. Dougweller (talk) 08:51, 5 April 2011 (UTC)[reply]
