How to delete
Hi,
You can find the delete button in the editing page of a content. To access that page, use the edit button in the content page, or just add /update/ to the end of the URL. Please note that this button/page is only visible to content owner. If you do not prove that you own a content, than you can't delete it. This is how our contribution system works. We stated this in the content form where you add new content: "Please note that if you do not prove that you own a content, you cannot delete it." (https://telegramic.org/bots/create/)
Thanks.
