Welcome
Welcome

Hello and welcome to Wikipedia. We appreciate encyclopedic contributions, but some of your recent contributions, such as your edit to the page Vitamin B12, seem to be advertising or for promotional purposes. Wikipedia does not allow advertising. For more information on this, see: If you still have questions, there is a new contributor's help page, or you can write   below this message along with a question and someone will be along to answer it shortly. You may also find the following pages useful for a general introduction to Wikipedia: I hope you enjoy editing Wikipedia! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. Feel free to write a note on the bottom of my talk page if you want to get in touch with me. Again, welcome! Doc James (talk · contribs · email) 06:02, 27 November 2011 (UTC)

Commercial links
Please do not add inappropriate external links to Wikipedia. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include (but are not limited to) links to personal web sites, links to web sites with which you are affiliated, and links that attract visitors to a web site 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. Clovis Sangrail (talk) 06:04, 27 November 2011 (UTC)

Please stop adding inappropriate external links to Wikipedia, as you did to Vitamin B12. 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.
