I got Pokémon Diamond today and I just can't stop playing it. My Pokémon are:

Prinplup level 17
Budew level 13
Staravia level 15

I just beat the first gym leader and I tried to get connected but sadly I didn't have any friend codes registered. Tell me yours so we can battle and trade! Mine is 1418 3252 7228, Name: Correia.

By the way, I have some questions for more experienced users. When I will be able to get older Pokémon via GTS? Because so far I just can seek for Pokémon I have already seen and I really wanted a Charmander as he is my favorite Pokémon. When will I get the National Dex?

And some noob questions. What is the Wi-fi club for and the Union?

I had to post this really quick as I want to play some more. Hope to see you guys on Wi-Fi.
