Definitely a big shame about the DS wireless services but what can you do? :< Hopefully you'll be able to pick up a 3DS and Pokemon X/Y soon - they're fantastic games. & I know, who wouldn't be excited for a R/S remake?! ..I guess I'm exaggerating a bit there, haha, but I'm reaaally anxious for its release since Hoenn was one of my favorite regions.
Anyways, welcome to PokeCommunity and such, XoneWolf! Hope you'll find all the trades you're looking for here. Am sure you won't have too many problems as the Trade Corner is bustling and a very fun section.
Have a splendid time exploring and let me or another staff member know if you need help. :')
