Well you know it shows you right on the page as it pings everyone - then it says done on the ones that went through which for me is usually all.
If you mean how do you check to be sure it really did it? Just go to Technorati and MyYahoo or one of the others sites it pings and check after a few minutes. Dont think you really need to though. It does what it is supposed to. Only thing would be if would miss one of the ping sites if it's down or times out I guess.
