there seems to be very little activity, and there is no separation of catagories. I typed in various subjects to search for, and it appears that there are few users here - that are asking very technical questions. I hope this improves, as the old forum is closing soon.
So far there are 2,406 registered Members. how many of those are bots/sleepers i do not know. No doubt people with either not register at all or move over when they are required to post net once the old forums are read only.
As to separation of categories users when creating a new post should really create tags to identify the subject matter more easily.
Discourse wouldn’t be my first choice of “forum” software, but it is what it is. I doe take a while to get use to this style of software.
