FYI - The ANGEL team has been looking at different ways to ease server load in finals week including temporarily deactivating a few processor intensive tools like course import and export.
If instructors teach a summer course, they should prepare a plan to import/export content between courses before finals week. They will be able to edit/add new material in summer courses and students will be able to upload/download files in all courses throughout finals.
See details at http://ets.tlt.psu.edu/angel/node/299. Specific questions can be directed to the ANGEL Help Desk form or angelsupport@psu.edu.
