My In-Series plugin is being taken over by a new developer, and has a new home at http://remstate.com/projects/in-series/. If you use In-Series, you should update your bookmarks and download the latest version.
Il Filosofo has released a new version of WP-DB Backup, as well. This version updates for the new scheduling functionality in the forthcoming WordPress 2.1 release. If you're a WP-DB Backup user, please be sure to update your bookmarks in order to keep up with Il Filosofo, since I'm no longer working on this plugin.
The link for the new version of WP-DB Backup is broken in the post. I've corrected it here.
Glad to see you've passed WP Backup into good hands :)
Thanks!
