Hello, I'm Jim1138. I noticed that you made a change to an article, Busan Exhibition and Convention Center, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Jim1138 (talk) 07:33, 18 February 2016 (UTC)
Please do not add promotional material to Wikipedia, as you did to Busan Exhibition and Convention Center. While objective prose about beliefs, products or services is acceptable, Wikipedia is not intended to be a vehicle for soapboxing, advertising or promotion. Thank you.
