Trac has me baffled

I'd like to file a bug against Cabal, but I cannot for the life of me figure out how to create an account at http://hackage.haskell.org/trac/hackage/ If there is a "create an account" knob somewhere, I cannot see it. For the record, the bug is that the sdist command doesn't archive files listed in "install-includes" to a tarball. The result is that if you try to build a tree unpacked from sdist, it will fail. I've seen this with a few packages.
