The promo tasks contest has been launched for over a week now but sadly most MMM participants are too focused on old Mavros release that they have not noticed this. Promo tasks is an initiative to bring in new members and this is very vital towards the sustainablity of the system.
Note that for every promo task you complete, you are rewarded weekly. So what is stopping you from making an extra cash with just few clicks from your laptop or few minutes of pressing your phone.?
