SMF uses autoincrement for the user-id. The same way that WP does as well.

Well, SMF actually deletes the record.

What I did is check the usermeta table for user_ids that do not exist
in the view. I then delete those records. That does leave an issue
with previous posts, links, and usermeta information possibly going to
the wrong user... That will have to be fixed.

Yeah, I keep that in mind when I enter info into the usermeta table. I
add the $wpdb->prefix to user_level and capabilities. That way it will
be set up properly for the blog.
