With any web based programme management tool one of the key issues is making sure that users are made aware of events that matter to them.
With Claromentis project manager this is achieved through a collaboration framework, news systems, various monitoring functionality and the ability of each user to set the notification systems that make sense to them - what do I need to be aware of and how is the best way to alert me :

In this case the user is requesting instant email notifications if tasks change in the project - but is not interested in alerts about changes in documents, for example.
This ability to control notifications is particularly important when the project management system is combined with extranet permissions to allow customers and suppliers direct access - unlike associates they are not going to be logged in on a long term basis and so need alerts to notify them that something has changed in the project.
