We have some news on the Assignment Calculator. We learned back in April, 2011 that the Calculator wasn't working with the then new version of Firefox. We added a disclaimer to the top of the page to have folks try it in another browser. We hoped the next version for Firefox might fix the problem but this has not happened. The Calculator has other issues and we have decided to remove the "beta" version as of September 2011.
Hopefully this is a temporary disruption and hopefully we will have more information to share soon.
Please also pass along any comments or questions--we are happy to follow up with individuals as needed.
