Trades and Specialties help?

Hello! Like the title says, I have some questions about Trades and Specialites. 

- For getting a trade- is that 5 completed threads in all or 5 completed threads when it pertrains to one thing? Do you have to have those 5 threads when the character is an adult wolf? Are you abel to do threads with only your character (without other people in it) to get those 5 threads if those threads have to pertain to that one thing? 

Those same questions are also for the other phases of it- since they seem to work the same?

I am aware that lone wolves can't get them without posting in matinence, right?
