Thank you!

We’re over the top…with gratitude for your generous show of support in our donations campaign this year.  We’re also over the top because we did better than our goal.

The money you contributed is much more powerful than you might imagine.  Not only did it attract a matching amount immediately, but it also provides us with funding we can use to provide the required matching money for new awards from government agencies.  It also is tangible evidence we indeed do have significant user support for what we do, a feature that also attracts more funding.
