I have a very important announcement to make...
Besides shouting "CANNONBALL!" I have created a Google spreadsheet that will list all the NWIC gamertag information.
All YOU have to do is click the following link, edit the list with your information, and voila! You can also sort the list by gamertag and Nasioc user id.
Feel free to add any columns you think might be needed. Anybody should be able to edit the information, so PLEASE don't delete other's info.
Ferg - feel free to update the original post with the link and I'll accept payment in the form of a get-out-of-time-out-free card.
