Think of LIVE channels like channels on Netflix or Disney+. They're just ways to organize different types of content, making it easier for you to find the livestreams you like!
For example - are you all about dungeon crawler games? Or manga? Do you just want to learn code and nothing else? Is Minecraft modding your thing? Or do you want to watch a real game developer pull together a game, live and from scratch, based on your input? Or are you that awesome thing, an absolute beginner? There's a channel for you!
Browse the different LIVE channels by clicking "Livestreams" on the main menu and then exploring each sub-menu item in the drop-down list. Find a channel and a livestream in the channel that you like, and then RSVP or play the video right there!
