When I first tried to sign up at Wilmott with my university email address, I never got sent a password, so I can't use that account. I was able to sign up through a friend's company email, then switch my profile email address to something@earthlink.net. I'm changing my Internet provider, so I will lose earthlink.net email address in 2 days. I can't change the profile email address to my university address -- it says it's already used by another account. It won't let me switch to a yahoo.com email address, saying:Sorry...Reason:This Public Email Address Is No Longer AcceptedCuriously, I still get sent a new password to the yahoo address after this, but if I try to login in with it, it says:Your login credentials were invalid.If you are experiencing difficulties logging in, contact the Forum administrator, or try logging in again.I can still use my old password after this.What email address can I use that will be valid?When I emailed admin when I first signed up, I never got a response.Could I get some help here?

Check your PM.

James, I'm having the same issue.Thank you for your help.

Please check your email? You should have your login details.

Well, after changing my email address in my profile, I have the following message "This Public Email Address Is No Longer Accepted"Then I receive an email with a new password on my new email address, but this password doesn't work (the old one still works)

We no longer allow use of Yahoo, Hotmail, MSN addresses etc. If you try to use one you may get locked out. You must use only a work/academic address. The system will send a new password (one that will work) to the new email address. If you continue to have problems, email me directly, james@wilmott.com.

ok now I understand thank you!
