25px Welcome to Wikipedia! Everyone is welcome to change pages here. We ask that you do not remove things from pages, as you did to "Integrated circuit", without giving a good reason in the change summary. If this was a mistake, do not worry. The change you made has been undone. If you want to practice changing Wikipedia, please use the sandbox. Thank you. --Egmontaz (talk) 14:31, 1 March 2010 (UTC)
25px Welcome to Wikipedia. Everyone is welcome to make helpful changes to the encyclopedia. However, please do not attack other editors, as you did on Call of Duty: Modern Warfare 2. If you disagree with changes, please talk about the changes and not the editors who made them. Take a look at the welcome page to learn more about changing Wikipedia. Thank you.
30px This is the only warning you will get for the bad changes you made. If you vandalize Wikipedia again, as you did to Justin Bieber, you will be blocked from editing. Either way (talk) 09:52, 10 May 2010 (UTC)

Hello, 18.104.22.168. An article you created Coolio cupcakeio, has been automatically tagged for deletion because it looks like a test page. Please use the sandbox for any other experiments you would like to do. If you think there has been an error please feel free to remove the tag and leave a message here explaining what happened. Thank you. --GoblinBot4 (talk) 09:44, 11 March 2011 (UTC)
25px Thank you for trying things out on Wikipedia. Your test worked, but because it had things in it which did not help improve the page, it was reverted or removed. Please use the sandbox if you would like to do more tests. You may also want to read the welcome page to learn about helping the Simple English Wikipedia. Thank you.
