Answer 2

There are three ways.

1. Go to Mystery Gift and click on "Recieve gift via Nintendo WFC"
2. Recieve my events from pokemondistributingcompany.weebly.com
3. Visit the Pokemon Global Link website (pokemongloballink.com) and go to the Promotions page and select an event then type down the password for the event (passwords are on my website pokemondistributingcompany.weebly.com)! If the password is correct and the event was a C-Gear Skin, go to the Customize page and select the C-Gear Skin that you got.

Hope this helps!
