I'm currently running a server with a modpack playthrough, and I'm still learning (total noob). A friend has been wanting to join me, not to interfere with my base, but to play on the same map independently. They'd like to watch, chat, and build their own stuff without touching mine. Basically, they want to play "with" me but not with me, if that makes sense.

I saw this mod in the recent list and it sounds like it might do exactly what I need. Before I try to use it in a way that might not be intended, I wanted to ask here: would it be possible to create just one extra team for my friend to join? I want them locked out of my force so they can't interact with my buildings or items, but still see the map, chat, and play on their own, a guest team essentially, or a config setting to enable just a guest teams and its own settings?

Thanks for any clarification!

Yes, MTS will help you with exactly that. But there are some nuances. There may be mods in your mix of mods that may not work will with MTS. If you give me a list of all your mods here, I can let you know if any of those mods will cause any issues. Good luck.
