Thanks for the update Ernie. Are you using the paid or free version? Any comment on the differences?

I try not to be too critical when considering new techniques and like to keep an open mind. It appears to be a good concept but very difficult to implement. Also, the last thing I need on a server of WordPress installs is a rogue cron job.

I am always looking at ways to diversify my links out of a blog network to non-blog sites.
