Welcome!
Hello, Mostasi10, and welcome to Wikipedia! My name is Shalor and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing. If you have any questions, please don't hesitate to contact me on my talk page. Shalor (Wiki Ed) (talk) 17:40, 30 April 2019 (UTC)

Mirrors
Thanks for contributing to the article S&P 1500. However, one of Wikipedia's core policies is that material must be verifiable and attributed to reliable sources. You have recently used citations which copied, or mirrored, material from Wikipedia. This leads to a circular reference and is not acceptable. Most mirrors are clearly labeled as such, but some are in violation of our license and do not provide the correct attribution. Please help by adding alternate sources to the article you edited! If you need any help or clarification, you can look at Help:Contents/Editing Wikipedia or ask at New contributors' help page, or just ask me. Thank you. Kuru  (talk)  01:04, 15 May 2019 (UTC)
