Hi thanks for your post, in fact I am new at this editing in Wikipedia, I am following your advice and starting to add references, I am trying to to follow the way the references were added in the same articles.
Hello, I'm Ronz. I noticed that you made changes to a number of articles without providing a reliable source. If you need guidance on referencing, please see the referencing for beginners tutorial. Please also note that medical claims have a higher standard for sourcing, as detailed in WP:MEDRS. --Ronz (talk) 19:58, 25 October 2013 (UTC)
