cool. I initiated the transfer on tradehill and sent to tradehill's okpay account, hopefully with all the correct numbers in the comment. Tradehill says "up to 24 hours" to get through, so I'm guessing it's some manual work involved.
thanks for pointing out and/or making this possible in the first place
hmm, so nothing has been credited yet on tradehill side, okpay payment to tradehill account OK856634147 went through instantly, will mail tradehill.
EDIT: 20 minutes after writing email to tradehill, the transfer got through. Thanks to okpay again and tradehill also
