This is actually my first discord also. Somehow i got auto-logged in when following an invite? No idea how exactly but my reddit login also works for discord.
Feels a lot like early slack.
Slack i only saw in the beginning until it became paid only and i felt not enough incentive to pay.

Regarding the questions, it is a pain to copy from discords pinned post.
I suggest you ask for discord users Gravewell and leviathan3k.
They will have the those questions compiled.

EDIT:
Netman over at discord made a txt file of the questions, her you go http://matland.be/fxnyquestions.txt
