I wish I could read your post before mining. I have joined dnote.poolnetwork.org I have the same problem with the "Edit Account". It said "A token was sent to your e-mail that will allow you to edit your account details" but I havent received any email for it. After log out and log in again, that sentence remain there but I cannot edit my payment address nor i can send email to my address anymore.

I wish this is not a SCAM. If it is, I guess Dnote you have to take some responsibility of that as you place such pool on your op.
PS: I have print-screened all of necessary information.

Edit1: After a while, I could press the button for sending the email in the pool. However, my mailbox still hasnt received any email for confirmation of editing the payment address.
