Two Problemos

Number one -> I'm trying to post in the discord server but -uhm- Im either dumb or something because I cannot find how to be able to type. I have literally pressed every single role like discord what more do you need of me. The only thing I can type in is in that 'introduction' subserver but everything else is locked for me to be able to write help-

Number two -> I've figured out [using amazing context clues] that there is something called 'Gems' as the site currency. I have no idea how to earn them and where I can see how many I have, so uhhh no powers or anything special for me until someone answers this or I figure these out myself lol-
