Actually... NO !
...and to answere the Question from PS2_-\'_\'-_PS2:
There are two fixed "Test-Nights" for each game (but you can also play whenever you want in a two weeks frame). The task is to be online so SONY can test the servers ! The more traffic, the more problems can ocure. After that, there is a special survey to fill out online. You can klick on some options like: errors while connected or if the menue is OK or stuff like that.
