Here:
http://docs.djangoproject.com/en/dev/ref/request-response/#django.http.HttpRequest.POST
it notes that request.POST is a QueryDict. The QueryDict getlist method is
described here:
http://docs.djangoproject.com/en/dev/ref/request-response/#django.http.QueryDict.getlist
Notice it does not take a default argument, as it returns an empty list if
the key doesn't exist. Thus you need to get rid of the default '' parameter
you had been passing to get. (Searching the docs for getlist brings up this
page as the first hit.)

This page:
http://docs.djangoproject.com/en/dev/ref/forms/validation/
covers form validation in some detail. It's the current version, so there
may be some differences for 0.96 (I don't recall, exactly), but the basic
structure, I believe, was there even in 0.96.
