I am not sure why https://gaming.stackexchange.com/questions/2752/pc-voice-chat-software-closed was closed... our leading FAQ proposal lists that questions regarding software tools which are commonly used by gamers are okay.
It's true that software like Fraps or Ventrilo can be used for many thing which aren't games; but it seems to me that they are still something commonly used by gamers, not to mention that I believe the overwhelming majority of Fraps and Ventrilo users are gamers.
And in any case, if that was closed, I'm not sure why How can I record demos of my gameplay? remains open...
