Hi there, DebbieChicharito, welcome to the forum! :D
As some of the regulars already mentioned, I'd definitely recommend you check out the Trade Corner and Battle Center for your trade/battle needs. NU/W is primarily a section for greeting new members rather than exchanging friend codes, so it would be much better if you moved your friend code over to your signature instead of your intro thread (which you can do by clicking "user options" and then "edit signature")! That way everyone will be able to see it underneath all of your posts. n_n
But anyway, hopefully you've been enjoying this amazing site so far! We're friendly, so we'd love to have you on board~! Enjoy your stay and feel free to message me if you need help, all right? :3
