A few questions on creating scenarios.

[Meggal_Bozale]

I've been trying to do more in-depth things on the map editor, but a couple things I could not find the answers for:

-What are the entity tags? How do I use them?
-Can I teleport players to different layers, like jailing people to a hell surface?
-Can I use surfaces to move power between layers? Can I power things like lights for a spawn without poles?
-How do I insert power armor with things inside it when people join?

I'm trying to learn now, is there anywhere that could help me learn how to make scenarios?
Thanks!
