Some useful information on the implementation of the GTD methodology within the Lotus Notes framework:
The David Allen Company has just released a GTD and Lotus Notes implementation guide, a worthwhile collection of tips and tricks on GTD and using Lotus Notes. Regardless of how you use Lotus Notes I think you'll find some helpful tips on how to configure and use Lotus Notes more effectively. If you are already a member of GTD connect, you can download the GTD and Lotus Notes implementation guide for free.
I've posted a few thoughts about the GTD and Lotus Notes guide and how to make your weekly review easier on my personal blog (here) where I often blog on the topic of Lotus Notes & GTD. You can also visit the DAC site to learn more.
I hope you find this information helpful.
Update: For Connect users, I see that Lisa just sent out an email with the free PDF download link.
