A fairly big update for today: you can now register at World of Switch. Click the Register link (top right), enter a display name, enter your email and choose a password - that's it.
Once logged in, you'll be able to add games to your Owned list or Wishlist by visiting the game page and looking for the buttons on the left-hand side of the page. To remove games from these lists, click the button again (it will change colour as you add/remove).
To see all the games on your lists, click on your name in the top-right corner, and click "Members index".
There will be more members-only features coming in the future. Sign up today to stay in the loop!
