Hello, I'm Materialscientist. I wanted to let you know that one or more external links you added to stairs have been removed because they seemed to be 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. Thank you.

I've removed your recent addition to Greenhouse as you had sourced it to a commercial website. We don't use WP to promote commercial sites. Vsmith (talk) 12:09, 5 May 2017 (UTC)
Please stop adding inappropriate external links to Wikipedia. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
