Boss member is a rank that currently exists however is not obtainable.
Simply once you get to senior member there is no higher title. My suggestion is to make this rank obtainable.
Currently the highest possible trophy points 446. If we minus the 5 point staff trophy you get 441. Boss member should be given awarded to users who reach a total of 441 trophy points maybe even 331 points (being the max amount of points that can be given for a non staff who has not reached 10k posts.

Anyway no matter how it is implemented it would be nice to have it obtainable.

 

Boss member exists here already otherwise I would not have suggested it.
Not everything suggested that is the same as mineverse is because of mineverse.
If you want to see copying look at the home page of skyblock and look at the forum infractions post.
Make mineverse special by changing rank names or whatever but my suggestion comes purely because skyblock gained a trophy that mineverse doesn't have therefore the extra rank seems like a cool thing to have.
