Hello, I'm Jab843. I wanted to let you know that I undid one of your recent contributions, such as the one you made to NMDA receptor, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, Jab843 (talk) 02:58, 7 February 2013 (UTC)

Hello, I'm Sam Sailor. I wanted to let you know that I undid one or more of your recent contributions to Propinquity because it did not appear constructive. If you would like to experiment, you can use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page.
