>From my limited understanding of Django... the admin.py stuff should not contain any save function.
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#ref-contrib-admin what exactly are you trying to do with the tag? Your M2M field in the initial Game class creates the relationship. You may want to looking into using the django-tagging app, which is what i used for my stupid little blog app (doesn't everyone create that first? lol ) If it helps, the first thing i did when learning django is follow the webmonkey.com django tutorial http://www.webmonkey.com/tutorial/Install_Django_and_Build_Your_First_App i found this infinitely more useful than the tutorial on djangoproject.com, as it goes into things a bit more complex and gives a greater idea on how things work together in the framework. Also, don't underestimate the framework... it does a lot of things for you, which is the point. It allows you to build an app quickly without worrying about the annoyances of SQL.
