You would have to delete your account and create a new one. Or create a second account with a new email so that you can still access the content from the first account.

Hello @Firefly thanks for your help when I signed up there was a facility to change your name which when I came to do it had gone, I used StanE got distracted and forget to add 'astMids' to it. I have sent a message to an administrator explaining, you never know
If I can't have it altered I will keep it as it is, I have put some info on my profiles thanks for that.
