Welcome
Hello and Welcome to Wikipedia. Thank you for your contributions. The following links will help you begin editing on Wikipedia:
 * The five pillars of Wikipedia
 * Contributing to Wikipedia
 * How to edit a page
 * Editing tutorial
 * Picture tutorial
 * How to write a great article
 * Naming conventions
 * Simplified Manual of Style


 * Please bear these points in mind while editing Wikipedia:
 * Respect copyrights – do not copy and paste text or images directly from other websites.
 * Maintain a neutral point of view – this is one of Wikipedia's core policies.
 * Take particular care while adding biographical material about a living person to any Wikipedia page and follow Wikipedia's Biography of Living Persons policy. Particularly, controversial and negative statements should be referenced with multiple reliable sources.
 * No edit warring or abuse of multiple accounts.
 * If you are testing, please use the Sandbox to [ do so].
 * Do not add troublesome content to any article, such as: copyrighted text, libel, advertising or promotional messages, and text that is not related to an article's subject. Deliberately adding such content or otherwise editing articles maliciously is considered vandalism; doing so will result in your account or IP being blocked from editing.
 * Do not use talk pages as discussion or forum pages as Wikipedia is not a forum.

The Wikipedia tutorial is a good place to start learning about Wikipedia. If you have any questions, see the help pages or add a question to the village pump. By the way, you can sign your name on Talk and discussion pages using four tildes, like this: &#126;&#126;&#126;&#126; (the software will replace them with your signature and the date). -Fnlayson (talk) 19:01, 19 May 2016 (UTC)

Welcome to Wikipedia but please note that we do not allow non-free images to be added to articles, have a look at some of the guidance in the links above. If you continue to add copyright images to wikipedia you may get blocked from editing so please take time to understand the policy and guidance on images, thanks.

Removal of copied material
Hello Ayon Biswas95, and welcome to Wikipedia. All or some of your addition(s) to GSAT-19 have been removed, as it appears to have added copyrighted material without evidence of permission from the copyright holder. While we appreciate your contributing to Wikipedia, there are certain things you must keep in mind about using information from your sources to avoid copyright or plagiarism issues here.


 * You can only copy/translate a small amount of a source, and you must mark what you take as a direct quotation with double quotation marks (") and cite the source using an inline citation. You can read about this at Non-free content in the sections on "text". See also Help:Referencing for beginners, for how to cite sources here.
 * Aside from limited quotation, you must put all information in your own words and structure, in proper paraphrase. Following the source's words too closely can create copyright problems, so it is not permitted here; see Close paraphrasing. (There is a college-level introduction to paraphrase, with examples, hosted by the Online Writing Lab of Purdue.) Even when using your own words, you are still, however, asked to cite your sources to verify information and to demonstrate that the content is not original research.
 * Our primary policy on using copyrighted content is Copyrights. You may also want to review Copy-paste.
 * If you own the copyright to the source you want to copy or are a designated agent, you may be able to license that text so that we can publish it here. However, there are steps that must be taken to verify that license before you do. See Donating copyrighted materials.
 * In very rare cases (that is, for sources that are public domain or compatibly licensed), it may be possible to include greater portions of a source text. However, please seek help at the help desk before adding such content to the article. 99.9% of sources may not be added in this way, so it is necessary to seek confirmation first. If you do confirm that a source is public domain or compatibly licensed, you will still need to provide full attribution; see Plagiarism for the steps you need to follow.
 * Also note that Wikipedia articles may not be copied or translated without attribution. If you want to copy or translate from another Wikipedia project or article, you can, but please follow the steps in Copying within Wikipedia.

It's very important that contributors understand and follow these practices, as policy requires that people who persistently do not must be blocked from editing. If you have any questions about this, you are welcome to leave me a message on my talk page. Thank you. NewYorkActuary (talk) 15:05, 5 June 2017 (UTC)

Be careful with citations and references when using Visual Edit
You have removed an important note in Comparison of orbital launch systems probably unintentionally because you have used Visual Edit. Please use 'Edit Source' for more concise editing so that you can be more detailed when editing complicated pages. standardengineer (talk) 14:52, 7 June 2017 (UTC)
