This is a current limitation - the
same email can not be used for admin and for member - since they have
different access rights/use different functions. We will eventually
work around this but it will be a while. For now you would have to use
a different email :-(
One trick you can use is to
add +something to your email. E.g. if your email is john@doe.com, you
can use john+1@doe.com and most email systems will ignore the "+1" part
so it will get to the same mailbox. So you will use john@doe.com for member email and john+admin@doe.com as admin email.
