Finally installed this and it works great, kind of...
The problem I am facing is, when this ext is enabled, I will get an initial email and if I follow the link provided in the email, it will take me to the new post since my last visit. But it doesnt clear the notification so if I dont manually clear my notifications and anyone else replies I will not get another email until I clear the notifications.
If I disable the ext and get the standard phpbb email, following the link provided will automatically clear the notification for that topic so new replies will get another email without having to manually clear the notifications. And sadly, this is a big issue for me as not all of my members will or are super tech savy and may not know or remember to clear their notifications and might not get any more emails until they do so.
I hope this makes sense and hopefully there is a way to fix this. Other then this issue, its great to have this extension back.
