Hello, and welcome to Wikipedia. I noticed that you removed some content from List of contemporary ethnic groups without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; I restored the removed content. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you!

Please do not add original research or novel syntheses of published material to articles as you apparently did to List of contemporary ethnic groups. Please cite a reliable source for all of your contributions. Thank you.

Hello, and welcome to Wikipedia. You appear to be engaged in an edit war with one or more editors according to your reverts at List of contemporary ethnic groups . Although repeatedly reverting or undoing another editor's contributions may seem necessary to protect your preferred version of a page, on Wikipedia this is usually seen as obstructing the normal editing process, and often creates animosity between editors. Instead of edit warring, please discuss the situation with the editor(s) involved and try to reach a consensus on the talk page.
If editors continue to revert to their preferred version they are likely to lose editing privileges. This isn't done to punish an editor, but to prevent the disruption caused by edit warring. In particular, editors should be aware of the three-revert rule, which says that an editor must not perform more than three reverts on a single page within a 24-hour period. Edit warring on Wikipedia is not acceptable in any amount, and violating the three-revert rule is very likely to lead to a loss of editing privileges. Thank you.
