In a recent edit to the page Betula pumila, you changed one or more words or styles from one national variety of English to another. Because Wikipedia has readers from all over the world, our policy is to respect national varieties of English in Wikipedia articles.
For a subject exclusively related to the United Kingdom (for example, a famous British person), use British English. For something related to the United States in the same way, use American English. For something related to another English-speaking country, such as Canada, Australia, or New Zealand, use the variety of English used there. For an international topic, use the form of English that the original author used.
In view of that, please don't change articles from one version of English to another, even if you don't normally use the version in which the article is written. Respect other people's versions of English. They, in turn, should respect yours. Other general guidelines on how Wikipedia articles are written can be found in the Manual of Style. If you have any questions about this, you can ask me on my talk page or visit the help desk. Thank you. Denisarona (talk) 15:59, 17 November 2013 (UTC)
Please refrain from making unconstructive edits to Wikipedia, as you did at Gulf Stream. Your edits appear to constitute vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Administrators have the ability to block users from editing if they repeatedly engage in vandalism. Thank you.

This is your only warning; if you vandalize Wikipedia again, as you did at Hieracium piloselloides, you may be blocked from editing without further notice. See also User:SummerPhD#Dynamic_IP_WP:ENGVAR_vandal. SummerPhD (talk) 17:53, 17 November 2013 (UTC)
