It would be nice to have a read latest replies (from your posts), or at least a way to see the newest posts made since your last visit (probably easier to do it that way)

Good idea. I will be adding some new features to the forums at some point. I want to add search and possibly this idea as well.

Another idea would have the option can be an email notification on a topic reply

"View Active Topics" was the only way I read the forums on the old version. I'd prefer to view these forums the same way.

or even to be able to see what topics and/or posts have read or unread content inside it
