User talk:Tutun12$

Welcome!

Hello, Tutun12$, 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! Here are a few other good links for newcomers:

 * Simplified 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, ask me on my talk page, or you can type   on your user page and someone will show up shortly to answer your questions. Again, welcome!

Hello, I'm DVdm. I noticed that you made a change to an article, String theory, but you didn't provide a proper secondary source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. DVdm (talk) 08:53, 12 August 2013 (UTC)


 * Note - Your addition has been reverted 3 times now. It needs wp:secondary sources. Please stop adding this. Thanks. - DVdm (talk) 08:57, 12 August 2013 (UTC)
