Been around forever. These guys provide a simple, highly-useful service... and they do it for free. What's not to like. The problem they solve is needing a static IP address when you've only got the dynamic address your ISP gives you. Using this simple service, you create a domain name such as myco.no-ip.com that regularly updates with your latest dynamic address. This allows you to do things like control your home PC using Remote Desktop Connection or run REST from your home and access it from anywhere in the world. Check out their Routers and Firewall Appliances Guides.
From their site... "A breakthrough book on productivity written by a dynamic author with national recognition, GETTING THINGS DONE has changed thousands of people's lives since it was originally published in hardcover in January 2001. Now five years later this book is a national best seller. This shows how valuable and effective this book has proved to anyone looking to achieve their goals in life and work with the minimum amount of stress and the maximum degree of efficiency and flexibility. Whether you are an executive, student, or run a business and/or household, GETTING THINGS DONE will teach you the tips and tricks of how to get--and stay--on top of it all." Highly recommended.
David Allen's book "Getting Things Done" has spawned dramatic improvements in productivity for many people. It's also spawned many adherents, devotees and gurus. Here you'll find a treasure trove of thinking on working on the way you work.
Do you get this type of message when you're trying to send bulk email? This Outlook security feature was introduced in Outlook 2000 (SR2 and newer), and installed by default with Outlook 2002 and Outlook 2003. This feature helps guard against problems but can be somewhat annoying. Especially if you use software such as REST which sends emails using Outlook. ClickYes Software solves this issue by allowing your email application to work without any delays.
Their site says: "Address Book Exporter is a little utility that does one thing, and one thing only: it will let you export your Mac OS X Address Book as a tab-delimited plain text file. Apple doesn't include this feature in its application, though you may want to have it to create mailing lists, upload address books to webmail servers, or whatever…" Nuf said.
