Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, adding content without citing a reliable source, as you did to San Francisco, is not consistent with our policy of verifiability. This is especially important when dealing with biographies of living people, but applies to all Wikipedia articles. Take a look at the welcome page to learn more about contributing to this encyclopedia. If you are already familiar with Wikipedia:Citing sources, please take this opportunity to add your reference to the article. Thank you. --Sfmammamia (talk) 01:22, 16 February 2008 (UTC)

San Francisco, California

Hey, I reverted your edit saying it snowed once in 2006 because it didn't have a source and, me being a San Francisco resident, I don't remember it snowing then. BoL (你好吗 • 生名) 02:07, 16 February 2008 (UTC)

3RR warning

If you are a new editor, you may not be aware that Wikipedia as a rule against making the same revert to the same article repeatedly. It's called the three-revert rule. It prohibits any user from making more than three reverts to the same page within a 24-hour period. If you continue to revert a change after having been warned of this rule, you may be blocked from editing. As I explained above, please do not insert material into the San Francisco article without a reliable source. --Sfmammamia (talk) 21:33, 16 February 2008 (UTC)

Welcome

Hello, Arad4, 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 have been reverted. 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.

There is a page about the verifiability policy that explains the policy in greater detail, and another that offers tips on the proper ways of citing sources. If you are stuck and looking for help, please come to the New contributors' help page, where experienced Wikipedians can answer any queries you have! Or, you can just type {{helpme}} 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 Wikipedia:Where to ask a question or ask me on my talk page. Again, welcome!  -Optigan13 (talk) 07:19, 17 February 2008 (UTC)

Arad4, as the message above indicates, it's great that you want to add the March 10, 2006 snowfall to the San Francisco article, but in order to do so successfully, you need to provide a reliable source. Wikipedia's standard is verifiability, not truth. Editors will be especially likely to remove something if you insert it in front of a source citation that does not include the information you just added. If CBS5 is your source, is there something on their website that references the snowfall? I looked in the Chronicle archive and couldn't find anything. Unfortunately, someone's privately shot video placed on YouTube, or an individual's photos placed on a blog posting or in a Flickr gallery, don't meet Wikipedia's standards for reliable sources. I encourage you to keep looking for a reliable source and add it back in once you've found one. --Sfmammamia (talk) 18:47, 17 February 2008 (UTC)
