Currently the system aggregates all replies to our posts (and the posts in which we left at least one comment) on the "Recent answers" page (http://filmaster.pl/odpowiedzi/ / http://filmaster.com/answers/).

We need an option to observe threads in which we never participated and unobserve the threads currently being observerd.

The database structure is ready for this. All we need is an ajax-enabled button next to each activity (preferably only on activity details page, i.e. the short review page, forum thread page of review page) to turn the notifications on / off.

The button can be located next to the "like" button (represented by a star).
