Copying within Wikipedia requires attribution
Thank you for your contributions to Wikipedia. It appears that you copied or moved text from United Nations Framework Convention on Climate Change to 2018 United Nations Climate Change Conference (your addition has since been removed). While you are welcome to re-use Wikipedia's content, here or elsewhere, Wikipedia's licensing does require that you provide attribution to the original contributor(s). When copying within Wikipedia, this is supplied at minimum in an edit summary at the page into which you've copied content. It is good practice, especially if copying is extensive, to also place a properly formatted copied template on the talk pages of the source and destination. If you have copied material between pages before, even if it was a long time ago, please provide attribution for that duplication. You can read more about the procedure and the reasons at Copying within Wikipedia. Thank you. — Diannaa 🍁 (talk) 21:19, 24 December 2018 (UTC)

Welcome
Hello, and welcome to Wikipedia! Thank you for your contributions; however, please remember the essential rule of respecting copyrights. Edits to Wikipedia may not contain material from copyrighted sources unless used with permission. It is almost never okay to copy extensive text out of a book or website and paste it into a Wikipedia article with little or no alteration, though you can clearly and briefly quote copyrighted text in the right circumstances. Content that does not comply with this legal rule must be removed. For more information on this, see:
 * Copying text from other sources
 * Policy on copyright
 * Frequently asked questions on Wikipedia's copyright policy
 * Policy and guideline on non-free content

If you still have questions, there is a new contributor's help page, or you can and someone will be along to answer it shortly. You may also find the following pages useful for a general introduction to Wikipedia:

I hope you enjoy editing Wikipedia! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. Feel free to write a note on the bottom of my talk page if you want to get in touch with me. Again, welcome! Wikiemirati (talk) 23:34, 25 December 2018 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did with this edit to Joseph Priestley. Your edits appear to be vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. Philipnelson99 (talk) 03:25, 26 December 2018 (UTC)

Recent edit to October Revolution
Hello, and welcome to Wikipedia. I noticed that you made a change to an article, October Revolution, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you! Happy holidays~!
