- Heya there, and welcome to CS!
Lots of people getting persuaded to come here by their friends lately, eh? c: Always makes me a bit envious, because when I tried to persuade my friends to join back then, they lost interest rather quickly :'D
Sounds like your friend is already doing their best in helping you with getting started, but if you do need any assistance or have questions, feel free to ask!
Good luck with your collection, I hope you'll enjoy your time here~
