Ok last question and I am just asking this because I want to be certain.
If you have a base (Don't have one yet, but may to do test before wipe), the only way people can find it is if you lead them there/they tag and follow you, or you add them to faction PC whilst using the computer as the leader of the faction, yes? I know you can't stumble upon another persons tent and I just want to make sure it's safe to use if I do make one so I can easily trade between my characters without using a tiny tent. the base I want to build has more stuff like a still for flamer fuel and all that.
Short version: the only way for someone to enter your player base is to add them to the list, invite them, lead them there of have them follow you, yes?
