Hello, I'm Katieh5584. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Bill Inmon, 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. Katieh5584 (talk) 12:17, 17 March 2014 (UTC)

Please refrain from making nonconstructive edits to Wikipedia, as you did at Bill Inmon with this edit. Your edits appear to constitute vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Administrators have the ability to block users from editing if they repeatedly engage in vandalism. Thank you.

Hello, I'm Oshwah. An edit you recently made to Lambda calculus seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to 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.  ~Oshwah~  (talk) (contribs)   16:12, 15 May 2018 (UTC)
