Welcome to GTW!
Gran Turismo Wiki is a wiki site, much like Wikipedia, that aims to create a comprehensive encyclopedia of all facts and tidbits related to Gran Turismo. GTW is the world's largest repository of Gran Turismo information. It is created, maintained, and edited by Gran Turismo fans from around the world.
Gran Turismo Wiki was founded in August 2008 by Gp75motorsports. Currently it has 3,586 articles with 88,254 edits between them.
This is a wiki site, which means anyone can edit. See that tab on the top of the page? Just click that and follow these steps to edit.
Edit? But I wanna create a whole new article!Edit
That's also simple. There's a link in the toolbar to the left hand side of the page that says "Create a page!" Open this link in a new window, click that, and follow the steps!
Darn! I need an image that doesn't exist here yet. Help!Edit
That's simple-just save the image, go to Special:Upload and click on "Browse". Unless you've saved a bazillion images since the one you want to upload, click on "Recent Documents", find it, click on it, hit "Save" at the bottom, and it's up!
