What does soft tag mean by the way
Soft tag basically means that you've not directly tagged someone (or a group), but they could respond to your post. An optional tag, if you will.
So, for instance.... Wu soft tagged the Disco & away team because what he wrote in his post *could* have been witnessed by people on the Disco or the away team, but it's not guaranteed that they did see it.
I soft tagged the away team, because one of them could come join my character, but right now nobody on the away team is close enough that they would hear what's happening.
