Welcome
Hello, and welcome to Wikipedia!

Someone using this IP address,, removed content from the page R-C coupled without giving an explanation. Please always provide an informative edit summary when removing content from pages. If is a shared IP address and you did not do this, you may wish to consider [ getting a username] to avoid confusion with other editors and further irrelevant notices.

Here are a few good links for newcomers:
 * The five pillars of Wikipedia
 * How to edit a page
 * Tips on starting your first article
 * Help pages
 * Tutorial

Here are some other hints and tips:
 * I recommend that you get a username. You don't have to log in to read or edit articles on Wikipedia, but  [ creating an account]  is quick, free and non-intrusive, requires no personal information, and there are many benefits of having a username. (If you edit without a username, your IP address is used to identify you instead.)
 * When using talk pages, please sign your name at the end of your messages by typing four tildes . This will automatically produce your username (or IP address) and the date.

I hope you enjoy editing here and being a Wikipedian! If you need help, check out Where to ask a question, ask me on my talk page, or type  here on your talk page and someone will show up shortly to answer your questions. Again, welcome!  Se by  15  41  06:43, 25 February 2019 (UTC)
