Auto creation of multisite blog on user registration

Question

I'm looking for a way to have users register on a multisite setup and have a blog automatically created for them... no, not the way the standard ms registration system handles it. I want to get rid of the second step in the process completely. They register as 'user', and a blog is automatically created at http://my.site.com/user for them.

Followup question... anyone know of a way of automatically pruning the multisite platform? IE, users who don't login for 'x' timeframe (or after a certain time period has elapsed) automatically have their site deleted.

I guess you are searching for the wpmu_create_blog() function. Just disable the standard registration process and attach this function to the regular registration. user_register is a good action hook to do this.

Regarding your second question I don't think there is a built in way. A good start is the wpmu_delete_blog() function. You could trigger this function on a regular base using wp-cron. The information when a blog was updated the last time is stored in wp_blogs in the last_updated column, but I don't think there is an API function to retrieve this either. So you'll maybe need a custom SQL query to get it.

This plugin by WPMU can help you for sure.
