You are trust level 2. Note that is specific to the charname-server, not Battlenet account wide. Each char has its own trust level it has to earn under the current WoW forum system. Changing name or server resets it to zero.
You can start with this thread one of our former Tech MVPs posted in 2018 when the forum software deployed.
You can also check the Discourse website to learn more about the forum software. They are the maker of it.
Basically, there are 4 trust levels:
- TL0 which is what an account starts as
- TL1 which you get in about ten mins just from reading posts/giving a like maybe?
- TL2 which takes repeated forum visits over a period of weeks, reading posts, and a few likes.
- TL3 which takes enough reading, likes, and visits over a 100 day period to earn. You have to keep that activity up to maintain it. A suspension removes that and you have to earn it back starting 6 months after it expires.
