Hello, I'm Elassint. I wanted to let you know that I removed one or more external links you added to Vacuum swing adsorption because they seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page or take a look at our guidelines about links. Thanks. Elassint Hi 02:45, 13 April 2018 (UTC)

Hello, I'm Jim1138. I noticed that you made a comment on the page User talk:Zanhe with this edit that didn't seem very civil, so I removed it. Wikipedia needs people like you and me to collaborate, so it’s one of our core principles to interact with one another in a polite and respectful manner. 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) 05:03, 20 June 2018 (UTC)
