About:
Spotter is software that can check students' answers to symbolic and
numerical problems in math and science. It recognizes an answer regardless
of the form it's in, and the instructor can put in helpful hints as
responses to frequently-occurring mistakes. Symbolic answers can be input
in a notation closely resembling normal human math notation (e.g., xy
rather than x*y, and sin x instead of sin(x)). Spotter runs as a Perl CGI
application on a Web server; the student doesn't need to install any
software.

Changes:
Better error handling has been added to the email functions. Users will
probably not notice any difference unless they use Spotter with OpenGrade
to send messages to students, and duplicate those messages via email.
