DND 5th Edition

Hi, I just noticed that some of the newer UA subclasses haven't been added to the Frontpage, but appear when you look at subclasses in the class pages. Does anyone one know how to add them to the frontpage? I would recommend looking at the rogue subclasses as an example.

Which subclasses are missing?

also, as for how to add classes to the front page, it seems that anything on the front page can only be edited by site administrators and the owner, so it may be good to be in contact with them directly
