User talk:Avandenborre

Welcome
Hello, Avandenborre, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your edits have not conformed to Wikipedia's verifiability policy, and may be removed if they have not yet been. Wikipedia articles should refer only to facts and interpretations that have been stated in print or on reputable websites or other forms of media. Always remember to provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles. As well, all new biographies of living people must contain at least one reliable source.

If you are stuck and looking for help, please see the guide for citing sources or come to the new contributors' help page, where experienced Wikipedians can answer any queries you have! Or, you can just type   on your user page, and someone will show up shortly to answer your questions. Here are a few other good links for newcomers:
 * The five pillars of Wikipedia
 * How to edit a page
 * Help pages
 * Tutorial
 * How to write a great article
 * Manual of Style

I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. If you have any questions, check out Where to ask a question or ask me on my talk page. Again, welcome! Calabe1992 14:05, 6 February 2012 (UTC)

I have reverted your edit for two reasons (sorry for not leaving an edit summary): (i) lack of references, (ii) Wikipedia must not give safety advice. Thus your addition is valid, but needs rephrasing and reference(s). I left a standard template below for referencing links. Regards. Materialscientist (talk) 14:07, 6 February 2012 (UTC)
