Hello, I'm Velella. I wanted to let you know that one or more of your recent contributions to Chitosan have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you.  Velella  ^{Velella Talk}   11:24, 15 October 2018 (UTC)[reply]

Welcome to Wikipedia. I saw that you edited or created Chitosan, and I noticed that your username, "Supplementsdiary", may not comply with our username policy. Please note that you may not use a username that represents the name of a company, group, organization, product, or website. Examples of usernames that are not allowed include "XYZ Company", "MyWidgetsUSA.com", and "Foobar Museum of Art". However, you are permitted to use a username that contains such a name if it identifies you individually, such as "Sara Smith at XYZ Company", "Mark at WidgetsUSA", or "FoobarFan87".

Please also note that Wikipedia does not allow accounts to be shared by multiple people, and that you may not advocate for or promote any company, group, organization, product, or website, regardless of your username. Please also read our paid editing policy and our conflict of interest guideline. If you are a single individual and are willing to contribute to Wikipedia in an unbiased manner, please request a change of username, by completing this form, choosing a username that complies with our username policy. If you believe that your username does not violate our policy, please leave a note here explaining why. Thank you.  Velella  ^{Velella Talk}   11:26, 15 October 2018 (UTC)[reply]
