EEk, site down, site back
Well, I figured I'd upgrade the Quills product from a previous subversion version to the latest... things went wrong... read on for details...

So it turns out that the install process somehow mangled up the skins for the Quills product. With no skins, there are no templates. No templates means no way to know how to display a weblog entry.
I fixed it by deleting the quills Filesystem Directory View and created a new one pointing to Quills/skins/Quills. This seems to have fixed it.
