The recount of the Ohio vote organized by the Green party needs about 1400 more volunteers as soon as possible. They have already posted the $113,000 bond (but still need more money to pay for organizing expenses, if you feel generous), but the real need is for people to act as observers, etc to keep the process honest. (You don't have to be from ohio, or a member of the Green party, to participate, btw.)

The recount effort also needs people in Ohio willing to provide housing and other services for the volunteers themselves (although if you live near the Ohio border, you might be able to help out there as well).
(And one snarky comment----Kerry keeps promising that all the votes will be counted, yet I haven't seen that him contribute one dime of his $15 million dollar slush fund to this recount project....)
