How to turn off email notifications from Unity Feedback Site?

Can anybody tell me how to turn off the Unity Feedback emails from http://feedback.unity3d.com/forums/15792-unity? Everyday I get several emails from this site, particularly the “Platforms: Linux Player / Web player Support” thread which is getting really annoying. While I sympathise with the Linux community, the demands made on that thread for Linux support begin to pale when answers by a Unity staff member have already been made on that thread and are seemingly ignored.
Please don’t turn this into a Linux bashing, or them and us thread. I just want to know how I can stop getting those emails. And yes I know I can block the emails or delete them.

Yeah I’d like to manage what threads I subscribe to. It’s useful for some threads but right now it auto subscribes me to all threads I post in…
