Why haven't I been promoted to the next Trust Level?

Continuing the discussion from An Explanation of Trust Levels:

Hey George,

Having reviewed your account, you meet all the criteria for promotion. Can you log out and close your browser window/tab for me? The promotion might be tied to the web browser session not being over. Let’s give that a shot. Please report back when you get the chance.

Hi @Pipstradamus
Can you explain me why I am not TL 3 ?
Thanx!
