Pleasure to meet you as well, Chuzzie!
Cirno and Hikari gave you a few things to check out, as well as places to go in case you have any questions or concerns. :D Cirny, along with any staff members & moderators in bold names, are very helpful and they are always around if you need any help. :) However, the most important thing to read is the rules, as every staff member will check to see if you are following them or not. You're new, so I don't want to see you breaking a rule this early on tbh D:
Another place you might want to check out is the Battle Server, which is linked in my siggy! It's a chatroom plus a battle simulator which allows you to battle. If you battle competitively, you can try out many of the tiers provided. You'll like it there, really!
Alas, don't be shy, stay out of trouble, and best of all, have a wonderful time here! <3
