Last year, I helped design and create a database application to track our location's on-site and off-site document retention, taking a lot of the manual work out of the process of finding out where a particular item is and determining what needs to be shipped out of the building. It's been in use here for some time now, and the people who use it regard it as a pretty important tool, if not quite indispensable.
It's now being implemented in one of the offices in NYC. Yup ... picked up for the home office. :) This is kinda like a local newspaper reporter being syndicated in the New York Times. Not front page, of course, somewhere back in the Business section, but still, very gratifying.
