For those of us that are subscribed to all 3 forums, it can be a bit confusing in the search results (today's posts, auto refresh, etc).
So I have introduced icons for each of the major sections.

VB doesnt make it easy and I had to add them to each one individually but it does quickly identify which 'forum' each post belongs to.

I may tweak the icons a bit over time but will see how this works.
