question about Unkown's tutorial for "Creating custom profile fields in SMF"

[marcnyc]

I have read Unkown's tutorial for "Creating custom profile fields in SMF" (http://www.unknownbrackets.com/tutorials/custom-profile) and I was just wondering: where in the database are these custom fields being stored? I don't see any extra fields in the smf_members table...

Also I was wondering, is it possibile to add extra fields to posts/calendar entries, meaning without altering the database to make upgrading easy?

Thanks

dont know about the second question, but the data from the custom profile fields is stored in the themes table.
