People new to Mastodon: Hello! Welcome! Have a seat, chill for a while ^.^ As with anything new, this will probably feel confusing and you might get inundated with sensory overload and all this New Stuff. Don't panic! Just sit and watch. Wait a few days. Let your butt imprint your masto-seat. Stuff will start becoming clearer. You'll settle in and find your people. You're used to one way, and this is another way - just give it some time. :)
