How to delete content?

How it is possible to remove content from LOGD?
Contributor users can remove their own content only. For Editors, it is possible to remove other people's content as well. Click on 'Edit' a page/demo/tutorial/etc. At the bottom you will find three buttons: 'Save', 'Preview' and 'Delete'. Click the last one. After that, confirm you want to delete that content.
