Hello, Celest. Welcome to PC, sis. ;D
Yeah, HG/SS sure are awesome. I've played the jap versions and am gonna download(yeah, I play ROMs. I just have to. D:) the English versions pretty soon. Actually, I've tried downloading them quite a few times. But...everytime I try, I fail due to some really weird reasons. D:
Anyways, have you read the rules and FAQ yet? If not, then it would be really good if you do. Rules can make you stay away from bad and unnecessary trouble while FAQ, on the other hand, may help in answering your questions about PC. And of course, if you still have any questions/doubts about the forum, just ask the staff team. They'll be sure to answer your queries/questions.
Have fun around the forums, Celest. Nice to meet you. ;D
