Here is an example to get a better understanding of this feature. Let’s imagine that you are browsing a computing forum. You would like to receive regular updates about everything concerning Nvidia. All you have to do is to enter the keyword "Nvidia" and validate this choice.
In this way, if a forum member creates a new topic titled « Looking for Nvidia drivers », you will be automatically alerted either by email or by PM of this new topic
Now let’s go further. Imagine that you start to receive way too many alerts and you’d rather be notified only about topics dealing with graphic card. Simply change your keyword to “Nvidia graphic card” and validate this choice.
Now you will not be alerted about topics like « Looking for Nvidia drivers ». You will, however, receive a notification for a topic like “Looking for drivers for Nvidia graphic card”.
