I agree that retired players should have a section of their own.
As for suspended players, each case should be separatedly analysed. Puerta will likely retire if he can't reduce his sentence and Canas can return this year in case he gets to reduce it. As for Beck, what exactly has he done to deserve an own forum? But since it's already been created, leave it the way it is.
BTW, Adam, I didn't see you asking to have Nadal's forum deleted when he was temporarily off the courts.
