You can use exactly the same software for @vimm as for Twitch. The only things you need to keep a close eye on are your bitrates and resolutions. I have done a few test streams, but @vimm recently did some changes, so I want to do a few new test runs again before I tell you what to do with regards to that. But OBS works, there's no need to change. They're a friendly and helpful bunch of guys, so feel free to get in touch with them as well. Here's a link to the @vimm Discord: https://discord.gg/GrNzJ7K
