Bug Reports & Feature Requests

Submit bug reports and feature requests at http://bugs.webwork.rochester.edu/. We can't fix bugs and add features if you don't tell us about them!

Patches

While we welcome patches of any sort, by patching against the latest CVS code, you save us and yourself time. A bug in this release may be fixed in CVS, and we can more easily handle patches against the latest code. Check out the latest development version from CVS and patch against that.
