Hello, I'm SarahStierch. I noticed that you recently removed some content from Outline of human–computer interaction without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, I restored the removed content. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! ''Please don't revert others changes without reasoning or explanation. Thanks!
