Wilmington Course PDF Files Updated

The PDF files available for download on the Mandarin Course from Wilmington page have been updated. The new files are dated May 9, and they now have a Table of Contents near the beginning, in addition to the Index at the end.

Also, as noted on the download page, in each file the headings in the Table of Contents and in the Index act as links to the indicated sections of the file. The headings of those sections in turn act as links back to the Table of Contents.
