The old MSKCC.org website was built using my custom content management system (CMS), called the Inettool.
Memorial-Sloan Kettering Cancer Center's website -- http://www.mskcc.org -- launched in 1996. Since 2000, I have been retained exclusively by Memorial-Sloan Kettering Cancer Center to build and maintain their external and internal websites.
For more information and screenshot about the CMS please visit my overview about the Inettool.
