If you were getting bored with MUGSI and SOLAR.
Updates:
Work continues on the data integration from the University system to McMaster's D2L system. The new basic, McMaster system will be launched in late June. Refinements will continue during June, July and early August in preparation for the stable, robust performance of the system during the Fall term.
ELM will not be available after August 31. All information (e.g. marks) must be removed (i.e. paper copies made, digital records copied) prior to that date. The University will have no mechanism to access information from the system after August 31.
