I've noticed lately that, if I tick the option for email notification of replies to a post I've made, I'll only get that notification for the first reply I get.
No more notifications are sent after that.
Some online forums have a system whereby you don't get any further notifications until you've clicked on the link to the notification already sent. However, that doesn't appear to be the case here, as there's no obvious way of reactivating this feature after the first notification.

Re: Issue with email notifications
Yes, so far here you can only subscribe to a single post, not to a whole topic. I'll be working on several forum enhancements soon, and this will be on the list.
