Problem:

What happens when information you commonly use is changed? Or a tool you have downloaded is updated? How will you know?

Qexchange Solution:

The Alerts module offers a set of personalized alert features to notify people when items of interested are added or updated. Alerts can be "pulled" by users on a subscription basis, or "pushed" to specific audiences by content owners.

Alert Me When This Item is Updated
Find an interesting item? Want to be alerted when it changes? Just check "alert me when this item is updated".

Alert Me When Something New is Added
Choose an area of interest to be alerted when anything new is added. Elect to be notified when you visit Qexchange, or by email.

Alert People that I Have Updated This Item
When you update one of your contributions to the knowledgebase, you can select which people to alert: those who have asked to be alerted, anyone who has rated or reviewed the item, or anyone who has retrieved the item.
