Cannot create an account with same name as support ticket+issues

I created a support ticket, and confused the "name" field with the requesters name, incorrectly assuming it would send an email. I am unable to modify the ticket to respond to requests for clarification without an account, and I cannot create an account with my name... I should probably just use a username instead. Once again, fooled by the name "name". Continuing; because it is already being used for a ticket name.
