Another idea - can you create two tabs - one for the blog feed and one for the forum feed. Maybe even add a comments feed and a send tips link.
You got me with that one, admin :^(
I've played with it for a few days and I've still had no luck. I even brought in my techie friends, and they can't figure it out either!
Unfortunately the parameter for controlling the feed source is within the attributes of the widget (I built this off of a template), which are kind of "set in stone". Changing the build of the widget would be like tearing down it's foundation, and starting again from scratch. I don't have the skill to do that, that's why I used a template in the first place!
Sorry about that :^(
However, I CAN make another widget specifically for the forum. And if you wish, I can make them for your other blogs as well. How does that sound?
