I've also got it recording submitter by userid as well, and backfilling that data where possible. And I've moved auto-approved into an attribute of users, rather than a hard-coded list of email addresses.
I do like rails migrations. Migrate to version=0, sync the database from the old system, migrate back to latest. boom, all my changes are applied to the database, everything's happy.
tomorrow I probably won't get much done on this. Stuff to do out of the house, stuff to do upstairs.
This weekend, I will work on the approval and signup controllers, as well as comments and categories if I get to them.
I should definitely have it ready for testing by the end of next week.
