Question

I have received several emails saying I have had a response from a post on this site, I have never commented on this post at all! What is going on?

Did you maybe press Subscribe?

Yup. I agree. You probably accidentally clicked on the 'Subscribe' button.

Take a look at the relevant thread to see if the usual 'Subscribe' button now shows 'Unsubscribe'. If so, it
(a) confirms your error and ;
(b) allows you to fix things by clicking on the button again.
