Hello, I'm INeedSupport. I noticed that you recently removed content from Uncertainty quantification without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please 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. Thanks. - I Need  Support -  (2019 Here We Come!) 20:07, 29 December 2018 (UTC)

Hello, I'm Sunmist. An edit you recently made to Cation-exchange capacity 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. Thank you. Sunmist (talk) 12:44, 13 February 2019 (UTC)
