Hi Hana! I'm Scotty, one of the creators of Tutturu.tv; you might have seen bumped into our name before, as there was some controversy a while back when Invited.tv copied our Terms of Service and Privacy Policy word-for-word ;P
If you're looking to edit your username, you can already do so on Tutturu! We also give you the ability to own multiple rooms, and have nicknames scoped on a room-by-room basis! (super useful if you're into things like DnD!)
Feel free to DM me on Discord (Scotty#1337) and I can give you a demo some time :)
