When you go downstairs in the Pokémon Centers in Platinum, next to the area where you have the attendant that lets you trade and battle with your friends, you will find a new attendant and another door. In here you will find the new WiFi club. The WiFi club is a new area that has many different activities that you and up to 19 other people can experience at the same time. There are several different servers and the people you go in with tend to be random

For example, making Poffin can now also be done over WiFi as opposed to just over Wireless. This time it is done through a new Mini-Game involving throwing Berries at a Swalot machine. If you succeed you get higher points and better Poffin for your Pokémon. Click here to go to the dedicated page regarding it

In the standard Wi-Fi room, instead of just having a list of the trainers that you can access whom are currently connected to Wi-Fi, you get a pseudo union-room type area where you go up to the trainers and ask them to trade or battle and they can respond in kind. You can still access the list mode from Diamond & Pearl in this as it works on the same system, this is just more visual

The Global Trading System has also had a massive tune-up in Pokémon Platinum. In addition to the trading of Pokémon in the same manner as Diamond & Pearl, the GTS also has many new features in the form of a Global Terminal

The GTS has a new feature. In the main menu of the game before you load your save, there is a new e-mail feature. Here, you have the ability to set your e-mail for several special features. You will need to confirm the e-mail address by conencting to the Wi-Fi Connection and allowing it to send you a validation code. The GTS has trading work exactly like it did in Diamond & Pearl, but now, if you have your e-mail set in the game, then when your trade on the GTS is completed, you will be notified by e-mail so you no longer have to keep checking back for it.

Dotted around the GTS are new global terminals. These give you access to a variety of Vs. Recorder functions. The Vs. Recorder is a new item obtained in Pokémon Platinum that allows you to record your battles. There appear to be several modes of the Vs. Recorder. It is likely there is a mode in the Global Terminal that allows you to send out your battles and receive battle recordings from your friends. In Browser Mode, which allows the item's use outside the GTS, you can view your own battles and battles your friends have sent you as well as expunge any battles you do not wish to keep.
