Hey OP, just a quick suggestion; it may be good to indicate on your site that payments will be made every Friday or Monday or Wednesday or whatever... Or maybe even every Tuesday and Saturday or something... That way, you can leave the tasks of having to pay out to one or two days out of the week instead of having to manually go through them as they come in. This way, you can actually enjoy your days off and use the other days to focus on marketing your faucet, rather than having to bounce back and forth with payments all the time.
Also, as you get larger (which you undoubtedly will), you'll be dealing with THOUSANDS of users (trust me), not hundreds like you currently have... This will make it easier to process, as well.
You should post here in this thread with every payment run (a link to your hash id would be great), and then specify why certain people weren't paid. Yes, this takes time to do, but with a high-paying faucet like yours, transparency will be the most important contributing factor to your success, and it's best to be an information admin, rather than the quiet dodgy ones we've seen so far with every site that has used the SatoshiNow script.
Just my 2 bits, but I think we would all appreciate if you were able to do that for us
I'll be hitting my withdraw threshold here today, so once I receive payment, I'm going to push the shit out of this site. Get ready for the traffic.
Cheers, and good luck!
