I changed the Discussions categories. You now have more options for categories on Discussions.
Below are the new Discussion categories.
General: For general discussion or discussion not covered by another category.
Wiki Announcements: For announcements about the wiki itself.
Wiki Discussion: For discussion about the wiki itself, such as discussing a suggested change in the formatting of a page.
Wiki Help: For obtaining help about a problem on the wiki. For example, a post about getting help implementing a template on a page would fit in this category.
Game Discussion: For conversations about the game series, like discussions about why you like your favorite track, or talking about potential ways to improve your times.
Game Help: For help on a game problem, mechanic, challenge, or getting troubleshooting tips for a ModNation Racers game.
I have moved existing Discussion posts to more relevant locations.
