On my account he set it up the same day. You only need to send account info once. There is no automated way to request a withdrawal you need to email support. You don't need to send account info on each request though. Low tech but it works and response time has been fantastic.
I was concerned about security and asked for a public key to encrypt the account details. He sent me his openSSL public key which I have no idea how to use. I asked him if he could provide a PGP key instead and he did within minutes.
TL/DR
shtylman is a pro!
Sometimes I don't respond to the ACH setup request right away. This does not mean there was a problem. Since most requests just send the info but don't wish to withdraw any funds at the time I just setup the ACH and wait until a withdraw request is sent. Soon it will be clear from your online profile that ACH is setup and no follow-up email will be required
Please contact the support email if we haven't responded to you already. We respond when your ACH has been sent out and if your request was over the weekend it would only be processed today.
