I was reading this [excellent post][1] about tzedakah and it seems that after a person is mafrish (designates monies as) tzedakah and the recipient disappears, he can give it to someone else. That made me [think][2] of the following question. 

Can you donate Tzedakah with no-one in mind? Does there have to be a poor needy intended recipient at the time of the donation for it to be considered Tzedakah, or is there a theoretical pool of Tzedakah money where I can donate money to and then later decide who will get it?
