Just about every school has a website. They come in all manner of types and their usage by parents varies greatly from school to school.
The biggest challenge with your school website, or any website for that matter is getting people to come and visit. It's not just enough to have one there. You need to encourage parents to come and access the information they need.
Konnective provides a great way to be able to push out a reminder or a snippet of news that then directs parents back to a website, an intranet, an online newsletter or any other communication tool. It works in concert with your other IT assets to bring immedicay, something that a website just can't do.
