Hello, I'm Walter Görlitz. I wanted to let you know that I removed an external link you added to the page White-box testing, 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.

I'm not quite sure you 1) don't discuss your changes, 2) don't explain your changes and additions in your edit summaries, and most importantly 3) don't understand what makes a reliable source. Not a single source you've added qualifies. --Walter Görlitz (talk) 19:37, 12 February 2013 (UTC)[reply]
Please find a reliable source. That PDF does not have an author and so could have been written by anyone, as student, a blogger or even you. Please stop now and learn what constitutes a reliable source! --Walter Görlitz (talk)
