I will be working on addressing the feedback that you all have provided about the new forums software. One of the items I see that needs more explanation is the ability to jump to points within a discussion without having to read through the whole thread.
The first way to navigate into a thread is just clicking on the thread title, which I don't think anyone is having any issues with.
The second is the little icon that looks like this

, when you click on that it will take you to the first post in that discussion that you have not read. The database keeps track of the posts that you have read/not read even if you are not subscribed to them. So you can use this for all discussions even though you have not posted to it. The icon only shows when there are unread posts in that discussion.
The third way to jump into the discussions is to click on the icon that looks like this

. It will jump you to the last post you made in that discussion. It's only shown when you have made a post to that specific discussion.
Please see the attached photo for exact placements of the icons.
