Some while ago, I had an issue with BOINC that led to me changing my email address for all projects. Unfortunately, a glitch occurred when changing the address for SETI@home Beta, and I now have two accounts for the one project.
A search for my nic will show two accounts opened on the same day, with the same name, etc.
This isn't the well-known "split CPID" issue.
Can the two accounts be merged, and if so, HOW?

Accounts cannot be merged.
But you can change your email and nick for the bulky account so it will appear only one account when doing a search for your nick

Cheers mate
I thought that would be the answer.
The glitch occurred when I changed my email.
When I tried to do this, I got a message telling me there was already a user with that email address!
It was me, on a different project. All I was doing, if I remember correctly, was trying to merge separate accounts under the one email, so I could stop using an email address that was under a heavy SPAM attack.
