egullet has the _highest_ quality forum I have seen anywhere. It might feel archaic, and there are lots of things it can be improved upon. But it works. And it has become a gem of information.
I am sure you are trying to learn from them and improve in the UI. But keep in mind, UI is expensive to do, and hard to do right. And if not done right, it gets on the way.
Egullet has taken a simplistic approach. The advantage is that their forum is the highest quality cooking forum on the internet. As I am about to post about my experience buying a Anova water circulator I discovered that I can't access my previous posting on that (same issue as "Where is my posting") and when I search there is no way to narrow my search. And there is no way to list my postings only (at least that I have been able to find).
My impression is that the improvements are not towards better content, but better look. So please, please, don't forget purpose and content. Think in terms of use-cases, and address them. I am sure, you, developers, are users of the forum, so do the OSS way and scratch your own itch too.
