After many weeks of constant hacking to the chat system in Need For Speed: World, it seems that the dev. team has no other choice but to disable this feature while it goes under maintenance (security fixes). Even though users will be able to communicate with each others in-game, free roam chat for everyone will no longer be in use. Here's their official quote on the matter:
Cars on sale!
In other news, six cars are now on sale with a 30% discount for limited time: Alfa Romeo 8C Competizione, Audi R8 5.2 FSI quattro, Chevrolet Corvette Z06 Carbon Limited Edition, Jaguar XKR, Ford Focus RS, and Pontiac Firebird Formula. If you wanted to have these cars in your garage but thought they were too expensive, here's your chance of getting them.
Volkswagen Scirocco Boy Racer and Toyota Supra Cop Edition
Two new cars are available in World: a custom edition of the Volkswagen Scirocco and a cop version of the Toyota Supra. The first is available in the car lot for 1750 Speedboost, while the Supra is a gift for anyone who buys 50000, 17500 or 8000 Speedboost.
