Can't change my name ...

[NotQuiteCockney]

If I try, I get an error about there already being a registration with my email address.

(It may be related: I can't see my history of name changes.)

Hi,
We've had a few of these over the last few days. It happens when we have two registrations with the same email address. This in turn happens if someone, say, registers with a home/work address then again with another address, then later changes that to match the first one. The system gets confused about who's logged in. I've merged them together and it should be OK now. If you log out then log in you should be able to name change and see your nickname history.

We're going to put something in place to stop it happening in future.

Regards,
Tech

Seems to be working now, thanks!
