Nice. Thanks for that.
But grrrr - I notice that the punbb devs still aren't including the forum **category** in the navigational bread-crumbs when you are in a topic.
All you see is: Forum root > Forum Name, where you should see: Forum root > Forum category > Forum name.
Or in the case of your example forum: PunDemo.org - PunBB example site > Test category > Test forum.
The absence of this is as annoying in 1.3 as it was in 1.2.x.
Even if the forum category name in the breadcrumb trail wasn't actually a clickable link to anything in punBB, but just displayed the simple category name, it would still be valuable to know.
