Selecting the class list's 'select/link' menu item before unzipping
the topic text does no harm and does no good: the ufg application
links to files that are on your SD card, not to files that are in a
zipped file on your PC. So, selecting the class list's 'select/link'
menu item _after_ unzipping the topic text is the recommended order.
The link token is another issue. The link token is the means by which
I get an overview of how often features (e.g., etymology viewer, photo
viewer) in the ufg application are used. The ufg application
increments feature use counters stored on your SD card. To encourage
users to submit those feature use counters, the ufg application does
not link to the free topic text unless the user has submitted the
feature use counters formatted as a link token file to the form at
http://eduneer.com/ssl/form/token.html. The purpose of the checksum
is to help prevent the user from accidentally or intentionally
modifying the contents of the feature use counter information in the
link token file. The link token enables the 'select/link' menu item
to link to the free topic text information for 30 days. Of course,
the 'select/link' menu item is typically used only after a user adds
new field guide information to the SD card. And once that information
is linked, it remains linked until the next selection of the 'select/
link' menu item (regardless of whether or not the link token has
expired its 30 day limit.) Because the link token is stored on the SD
card, it lasts for 30 days even if the ufg application is deleted and
reinstalled.
