Just to the issue of pms from E-I being sent to your outside email.

You can change the email address anytime by clicking on the “edit email and password” link on the left hand side of the screen when you are in your pm area or you can opt to delete the email address you provided on joining from the two panels that you will see your address contained within and click on “save changes” and you will then only have a pm sent to E-I inbox only.
