I added a new classification today that includes a bunch of Port of Entry taxa. When I imported a batch of POE specimen data, all of the taxa that were not included in the original classification were automatically added. This resulted in a messy looking tinytax for the Ant taxa page. To remedy the situation I had to delete the existing 'Ant taxa' taxonomy, do up a new excel spreadsheet with all the POE taxa included and properly entered, then import it as a new biological classification. I eventually figured out that the parent/child nesting of the terms is dependent upon parents preceding their children in the spreadsheet itself.
I also did a test run of the Biblio content type, and imported a batch of endnote citations. The result is not perfect, but it is very easy to do and the layout is already very nice.
