Just checked this thread, and I see that I used a Comment here, and there ARE subsequent new items, so there seems NOT to be any problem?

Replies can be made as normal to the thread, but can not specifically be made for the replies that are "comments" instead. Literally the only thing I can do with the comment is "Delete". No reply, no quote, no up or down vote (no ban user

). So yes, seems to be another issue with the forum. It also appears that most users (myself included) do not even have the option to comment rather than reply.
I also still have not received a reply from the "Contact Us" form submission about the missing New Post button.
