@Bultaco : If you wish to modify your subscriptions (e-mail notices, etc). click on your avatar at the top right of the screen after logging in, then go to "My Subscriptions", then "Notification Settings" and set it up the way you want. Check out any other settings you have there so that the forum works the way you want. The default settings of any forum, TV, set-top-box, etc are rarely what you want, so you need to set things up to optimize your settings.
For example, I have mine set up to e-mail me if there's a new post in a thread where I'm participating, or if I'm mentioned. You may have different preferences, but you need to change those preferences to what you want.
