If you click on "all tags", and click on one of the tags on that list, 
you get a 404 because the URL doesn't contain ROOTDIR.  So on my site, 
for example, I get:

    http://scoop.morris.umn.edu/tag/introduction

when I should get:

    http://scoop.morris.umn.edu/scoop/tag/introduction

Interestingly, if I click on the link for a tag on a particular article, 
I get the correct URL, which smells of duplicated logic...

I had a quick look for which box would generate that URL and didn't turn 
it up.  I'd appreciate a pointer if someone knows it.

Thanks,
