Guild Wars 2

I just have one question about name display. I noticed that some players have 2 stars in title and others have only 1. I have no idea how many stars are in my title, and no idea how to check how others see my nickname and titles.

So I’m wondering what’s the deal with those golden stars?
I’m attaching photo below with bost pictures … as said before, on one picture there is only 1 star in player’s name and on another there are two stars.

Anyone mind explaining newbies (me obviously xD), what’s the deal with that?

The star on the left is for World Completion,(visiting every single hero point, vista, point of interest, and way point on the original map) the one on the right is for Masteries.

Thanks for your answer, just what I needed to know
