Tried editing some of the pages for the new humanities site using Contribute. The styletag dropdowns are not intuitive, but seem to work more or less. Have not tested styling using spans, but block elements are working and selecting text and applying an em tag is working.

Creating a relative link to a pdf, rtf or doc file requires that you open the link window to a web page on site, then click the advanced button and enter the filename in the href field - leave the URL field empty. If you try to put the filename in the href field you get a malformed URL because Contribute prepends the "http://" protocol wrongly.
