This could be an extremely easy - and very versatile - option for communicating with your school community.

Either as an entire web site, or as an extension of an exisiting site, which can be "modularised" to provide editing access to multiple teachers/students from home.

For example - how about an excursion monitor which can be linked to your school's website, and can be updated easily from a teacher's home before breakfast?

Lots of posibilities!
