The WebLearn service will be unavailable sometime between 7am and 9am on Tuesday the 27th of September for an upgrade to version 2.6-ox9. (It was hoped that we would move to version 2.8-ox1 on this date but this has not been possible and will now happen in January 2012.)
It is advisable to avoid using the WebLearn service between these hours to avoid interruptions. Sorry for any inconvenience.
