Why is there a welcome message for TL-1 users but not new TL-0 users?

Hi @MikeNolan !
Just wondering, why do new users start at TL0 OR TL1?
On another forum I’m on, TL0 new users get the welcome message (This is the first time xxx has posted, let’s welcome them to the community!) when they make their first post.
Unless, you are referring to the one by discobot?
