First, you would probably have to register with the Netcentrics forums to post a question there (just as you have to on these forums here) but I donít think you have to register the software to post there. Alternatively, you could call Netcentrics, just as I did a week ago when I had a question.
Iíve had some experience with uninstalling the Netcentrics add-in and it was pretty benign. It had no effect on my folder structure. If I recall correctly, some of the GTD-specific commands still appeared in some of the drop-down menus, but I was able to remove those and all vestiges of the program.
FWIW, I was a very early adopter of the add-in but in a quest for something better uninstalled it several months ago while flirting with Clear Context and reading the Linenberger book. But now, Iím using the Netcentrics add-in with Outlook 2007óand OneNote 2007 and MindManager as companion piecesóand Iím quite pleased with the combination. (Itís been written that Outlook is probably the least-changed of the Office 2007 suite applications, but I find the improvements quite profound.)
Of course, itís always wise to make a backup of your Outlook files before attempting any major change. When Iíve tested new Outlook add-ins and combinations Iíve tried them on a laptop first, before moving them to my mission-critical desk computer. If testing it on a second computer is an option for you, I would recommend that you print out the pdf userís manual that installs with the add-in and reading through the first 82 pages of the manual. Itís an excellent treatise on using the add-in to best effect. (The remainder of the manual appears to be the Davidco whitepaper on setting up Outlook manually.) If testing the add-in on a second computer isnít an option, I would suggest that you try to set aside a few to several uninterrupted hours to work through the manual and set up your ďworkĒ computer with the add-in.
The screen shots in the manual appear to be of Outlook 2003. I hope Netcentrics (or Davidco) comes out with another edition of the manual with Outlook 2007 and some guidance on using some of the new OL2007 features in a GTD environment. I purchased Marc Orchantís new book ďThe Unofficial Guide to MS Outlook 2007Ē and find it a great help and a tremendous value. Mr. Orchant is a black belt GTD practitioner and certainly no stranger to these forums. Iíve gained much good advice from reading his blogs over the years, so picking up a copy of his book when I made the switch to OL2007 was a no-brainer; even though itís not a treatise on using New Outlook in a GTD environment. Unfortunately, I have a great deal going on right now and have been able to read his book only when I can steal away a few moments here and there, but every time I open it up I seem to pick up another trick or technique the value of which will likely exceed, over time, what I paid for the book ($18.99 retail, 500+ pages).
