You should see it here listed here

and a direct link is here

If that does not bring it back please check your

Check "Edit Options"
Make sure
Thread Display Options ->Default Thread Age Cut Off
is set to
"Show all Threads"
As if it is set to less than 100 days you wont see anything in that forum (as it has been pretty quiet there).
If you still don't see anything there let me know as there might be some additional security issues.
