Hello, and thank you for your contributions to Wikipedia! I noticed that you recently added commentary to an article, Willem Johan Kolff. While Wikipedia welcomes editors' opinions on an article and how it could be changed, these comments are more appropriate for the article's accompanying talk page. If you post your comments there, other editors working on the same article will notice and respond to them and your comments will not disrupt the flow of the article. Thank you.

Welcome to Wikipedia. Although everyone is welcome to make constructive contributions to Wikipedia, at least one of your recent edits, such as the one you made to Pierre-Auguste Renoir, did not appear to be constructive and has been reverted or removed. Please use the sandbox for any test edits you would like to make, and take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you.

Welcome to Wikipedia. The you made to Twilight (novel) has been reverted, as it appears to be unconstructive. Use the sandbox for testing; if you believe the edit was constructive, ensure that you provide an informative edit summary. You may also wish to read the introduction to editing. Thank you.
