Is there a way to find out if a site has been created or deleted ? I tried the onCreateNode behaviour, but it seems there are multiple nodes created once you create a site. So the behaviour get called multiple times.
Sites are created and deleted below /Sites folder structure in the repo, so you can create simple rules for sending notifications with js api, when a folder is created or deleted at this level. Maybe it's a simpler aprox. than a content behaviour.
