It is a shame you felt so out of place. I belong to a guild and it has "New Member Coordinater". Takes the new ones under her wing for a time and shows them the system. Explains different tables and is available if person has questions.
Ask next time if that guild has one . if they don't maybe you can suggest an experienced person could take on the job as you feel so lost there. That's how ours got started. Makes it so much more welcoming.
