I've created a request "Provide help." I'm waiting for a week and nothing happens (it is still marked "on the dispatcher's waiting list"). Also I don't understand, will a recipient decide to take help proposition or the system. E.g. some user provides help of 0.023 BTC. It is relatively unique so the user will have to wait until someone needs exactly 0.023 BTC. He will wait for weeks, while requests for a round sum (e.g. 0.02 or 1.00 BTC) will be accepted more often. Is it correct?
