Hello, I'm Velella. I wanted to let you know that one or more of your recent contributions to Building management system 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 17:09, 1 September 2019 (UTC)
 * If this is a shared IP address, and you did not make the edits referred to above, consider creating an account for yourself or logging in with an existing account so that you can avoid further irrelevant notices.

Please do not add inappropriate external links to Wikipedia, as you did with this edit to Free Software Magazine. Wikipedia is not a collection of links nor should it be used for advertising or promotion. Inappropriate links may include, but are not limited to, links to personal websites, links to websites with which you are affiliated and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the article, please discuss it on the article's talk page rather than re-adding it. Thank you. - Frood (talk!) 04:10, 8 September 2019 (UTC)
