     * Extraction of vector images and tables from within the document is also not supported.
     * Some PDFs use special glyphs to represent ll or ff or fi, etc. Conversion of these may or may not work depending on just how they are represented internally in the PDF.
     * Some PDFs store their images upside down with a rotation instruction, |app| currently doesn't support that instruction, so the images will be rotated in the output as well. 
+    * Links and Tables of Contents are not supported
 
 To re-iterate **PDF is a really, really bad** format to use as input. If you absolutely must use PDF, then be prepared for an
 output ranging anywhere from decent to unusable, depending on the input PDF.

 How does |app| manage collections on my SONY reader?

@@ -450,6 +461,11 @@ How do I use purchased EPUB books with |app|?
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 Most purchased EPUB books have `DRM <http://wiki.mobileread.com/wiki/DRM>`_. This prevents |app| from opening them. You can still use |app| to store and transfer them to your e-book reader. First, you must authorize your reader on a windows machine with Adobe Digital Editions. Once this is done, EPUB books transferred with |app| will work fine on your reader. When you purchase an epub book from a website, you will get an ".acsm" file. This file should be opened with Adobe Digital Editions, which will then download the actual ".epub" e-book. The e-book file will be stored in the folder "My Digital Editions", from where you can add it to |app|.
 
+I am getting a "Permission Denied" error?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A permission denied error can occur because of many possible reasons, none of them having anything to do with |app|. You can get permission denied errors if you are using an SD card with write protect enabled. Or if you, or some program you used changed the file permissions of the files in question to read only. Or if there is a filesystem error on the device which caused your operating system to mount the filesystem in read only mode or mark a particular file as read only pending recovery. Or if the files have their owner set to a user other than you. You will need to fix the underlying cause of the permissions error before resuming to use |app|. Read the error message carefully, see what file it points to and fix the permissions on that file.
