I'm lovin Atahualpa so far but I'm trying to figure out how to conditionally exclude widgets from the sidebar. I want to show my Archives and Categories on my posting pages only and exclude them from my normal wordpress pages. I tried a plugin called widget-locationizer that didn't work for me.

Any suggestions?

I use widget locationizer and it works fine for me. What didn't work for you?

Widget Logic plugin works equally well and works by interfacing with PHP so perhaps more powerful (although more complicated) and also Advanced Text Widget will work if you put conditonal php logic inside the text widget as well
