I would like to become a GM

Hi,
I would like to become a GM here, I asked another gm for assistance and all he told me was to come on fouroms.
So that's why I'm here:D
I know most of the commands, and I used to be a GM in Naxpgaming so I have experience.
I also have ALOT of free time wich means I can spend alot of time helping the players with their issues.
Can an Admin or another Gm please tell me if I can join the wow terra staff please? ( on this topic)
Thanks alot
