Welcome back to the forums, Jamie! Nice to see you come back with OR/AS given how many people have been getting back into the games by revisiting the beauty of Hoenn in a new 3D look.
If you're interested in battling and trading we have both the Trade Corner and Battling & Team Building sections which have everything about battling and trading covered, so hopefully those sections will keep you busy, and you can always leave your Friend Code over in the X & Y section's Friend Codes thread as well. I still haven't played OR/AS yet, but I plan to get them sometime around Christmas but if not exactly around there, maybe sometime a bit after then. I already know which starter I'm picking, the one I always picked in my old Hoenn games, good ol' Mudkip!
Have fun settling in again Jamie, and if you ever need anything we're always here to help! Have a great time as well, and stick around hopefully! See you around, okay?
