Can I add a contact to myself at the end of the article?

Of course you can, but please note that by doing this you share your contact with all the people who downloaded the issue that contains your article (sometimes several thousand people), so consider adding a contact, because we do not have an influence on who will write to you or call you. But of course it’s also a great way to make contacts with the hakin9 community - e.g. some of our authors found a new job this way (someone from some company saw their article, was impressed by it and wanted to have such an expert in their team!). Also, sometimes readers have question to the author and thanks to your contact mentioned in the article, they can reach out to you!
