Discord is a useful app that is used by a lot of Steemit users as a means of communication. There are some very big groups over there that have thousands of members, and you have the opportunity to join the groups and it is great for networking and promoting your art. I will post the website for discord. We can also use it to direct message each other about collaborating :) once you have it I will send you some invites to some great groups to join
