Good to see that this has already been handled, but FTR:
The only things I can think of that might be out of IT Security's realm here, would be some particular "how do I use" or other "application troubleshooting" questions which more appropriately belong on SU/SF. There's also the usually off-topic "shopping recommendation" types and such, which would just be closed no matter where they are in SE.
So, unless anyone else can think of a subset of Computer Forensics questions which fits the SE model, is off-topic on any other current SE site, and is large enough to be worth making its own site, I agree with the proposal closure.
