Hello @trinityfarms,
When one create a new account, the trust level is 0, and there are limitations, like crating a new post (thread). You can reach trust level 1 withing a short period by engaging with the forum, visiting, reading posts, liking posts, interracting, etc. (Maybe following the tutorial is helping?) It depends how it has been configured on this server.
The other way is an admin promoting you immediately. They have the power to flip the switch on! 
Usually @William does that to users that ask, just as you did here. (When he will see, he will most probably make it possible for you too, instead of the more “lenghtier” process of gaining trust level 1.)
Kind regard!
