Well done, my friends! At last you see the final task. But it has two hard stages.
At first, you have to speak with that man whose name you know from the previous step. Facebook as well as Skype are at your service. This hint will help you find him there. At the beginning, tell him, please, what media you like. Then, you should add some facts about it, describe your favourite example, explain its pros and cons and at the end you have to share your own point of view.
Oh, I nearly forgot to say about one important thing. If he is satisfied your tellings he will propose you to ask him different questions. So, if you want to find the valuable key in order to unlock the last quest room, it would be necessary to wonder what are his favourites.
