It's really fun when the same problem keeps turning up with every second forum software upgrade.
This time the fun is that after setting an alert on a thread after reading several replies in the thread in the browser, you then are able to read those same replies again. Because, yes, they are sent to you as alerts.
Could we *please* get back to the logical state of only getting alerts for posts made to a thread *after* we have set the alert ? (Again)
