I would like to invite you all to Clan Nyura, where we're currently holding NetBattle tournaments and will soon do for Pokémon Diamond/Pearl on Wi-Fi. We're currently also having quite a lot of board games happening with prizes, which sometimes could include Pokémon. Not only that, but we also offer a few services like a Restart Bank, Classifieds and a Wi-Fi Shop, alongside other shops. Spriting competitions always take place for those that like to edit/make sprites, and we're currently having one. But more than that, we're a tight community always welcoming new members.
For more info, you can access the site through my sig, as well as you can access the forums from the site. But of course, if there are questions, I'd be happy to answer them.
