Five emails arrived indicating this same post. What's happening?

Is there no way to resolve this? I just received three emails from the same post! I want to configure it to stop receiving emails, but I couldn't find that option anywhere...

At the top of the topic's page is a subscribe button, with a wrench... the wrench is a button for the subscription/notification tools.

Thanks. I clicked the button and set "off" to both options. As the big one is too big I had to zoom 30% in Firefox, to click the save button. I think that solves it...

Ja the big menu does not scroll. :-/
