Changing email address changes the CPID which is used to roll up different projects at 3rd party statistics sites. If the email address is the same as used to register at all your other projects, than nothing changes as the oldest CPID associated with that email address is used for roll-up purposes. Sometimes it takes several days to auto-realign everything.

The message does not suggest so, but since a few years you can no longer have same email address on multiple accounts. You might want to check.

PS, would remove the mail address from your post as spammers and hackers love to add it to their table. Rather, write to the Contact Us if you cant resolve this.

Hello 'adrianxw',

Your email provider is not allowing our database to send you emails. This means that you will not be able to receive any email communications sent from World Community Grid (eblasts, password reset, etc.). Do you have another email address you can use?

We recommend you adding the following email addresses to your whitelist or contact list via your email provider:
support @ worldcommunitygrid.org
wcgrid @ us.ibm.com
noreply @ worldcommunitygrid.org

We also suggest you contacting your email provider to report the email addresses above as legitimate email address, and not spam.

Thank you for your support,
ErikaT

You can (un)tick your dead accounts to not be send mails by WCG. As before, you can have only unique email addresses on your accounts, so 3 accounts, 3 different addresses are required, no duplicates, and no there's no merge functionality at WCG, not for accounts, not for devices.
