Hi - my profile name was initially set to our email address hello@.... and displays as 'hello'?

I 've tried to update it to 'Aerialview' several times but the page keeps throwing an error. Can someone change this for me as I think it's a bug due to the @ in the user name.

Thanks

What's your browser?
Try with chrome, here it worked with him.
Username not used yet?
