December 2011 edit
Hello and welcome! I noticed you made a change to an article, but didn’t provide a source for your edit. I’ve removed it for now, but if you can include a citation to a reliable source and re-add it, please do so! Thank you, Jim1138 (talk) 08:39, 22 December 2011 (UTC)
==I did not make any change to any article. What article? It was to a discussion page and i think you do not need citations for discussion page. I am changing it back. Thanks but no thanks for your input.(talk) 08:39, 22 December 2011 (UTC)
August 2022 edit
Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Invention, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. Padgriffin Griffin's Nest 02:38, 1 August 2022 (UTC)
