Hello, I'm Jschnur. I wanted to let you know that I removed an external link you added to the page Cathode, because it seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.

Please do not add inappropriate external links to Wikipedia. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include (but are not limited to) links to personal web sites, links to web sites with which you are affiliated, and links that attract visitors to a web site or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it. Thank you. Materialscientist (talk) 14:17, 19 April 2013 (UTC)

Your recent edits

Hello and welcome to Wikipedia. When you add content to talk pages and Wikipedia pages that have open discussion, please be sure to sign your posts. There are two ways to do this. Either:

1. Add four tildes ( ~~~~ ) at the end of your comment; or
2. With the cursor positioned at the end of your comment, click on the signature button ( or ) located above the edit window.

This will automatically insert a signature with your username or IP address and the time you posted the comment. This information is necessary to allow other editors to easily see who wrote what and when.

Thank you. --SineBot (talk) 16:11, 19 April 2013 (UTC)
