Donating to a private party and claiming on my taxes?

Here in Green Bay, WI we have a facebook page called "Lifting up Green Bay".  It is used for those in need; ie: lost everything in a fire, left a bad relationship and starting over, school supplies, etc.

If I donated items (furniture, kitchen household items, school supplies, etc), can i still claim this as a donation on my taxes?  If so, what do i need to do?
