You have the option to watch any thread you like and to receive emails when there are new posts in that thread. It is Netrider's way of keeping you updated on threads you have created, participated in, or choose to be updated about. By default any thread you start or reply to will become watched. This will generate an email to you every time someone replies as well as an alert on the Alert's menu. You can change this behavior in your preferences. To watch a thread without participating, simply go to the thread you want to watch and click on Watch Thread in the top right of the thread. You will get this pop up asking if you want to receive email notifications if someone posts in that thread from now onwards. To view all your watched threads just simply go to your Name at the top of the page and click on Watched Threads. This will take you to a page that will show your watched threads if they have new posts in them. To view that thread just click on it.
