First of all, really enjoying the new changes that was created in the new website. The forum looks kick ass. Can’t wait to interact more with the peers of GregMAT through the forum. 
I understand that the forum’s view is still in the initial iteration of customer testing. So I would like to provide some feedback which, I hope would help you if you are looking to modify how the Forum’s page looks like.
The problem that I faced was that I found it very difficult to navigate through the website for forums. So I designed a simple view that could possibly solve this issue. I am attaching a mockup of the view that I thought about below.
In this view, everything will be in just one page and the view would be similar to discord. This would make the experience of navigating through the forum’s page very easy and enjoyable. I hope this would help 
I am sorry for using the wrong category, I think a new category where people can post about improvements on the website would help I guess
