Moodle in Schools is closing. http://www.moodleinschools.org.nz/forum/topics/91323
The website is closing on in 6 days: 15th June. Until then you can download resources (etc) off the website.
End of an era.
As the post says, this really is a result of the progress in the regular Moodle: many of the features that made MIS attractive are now in standard Moodle.
