Christian name duplicated when registering

[vinpet.z4sdcau]

  Somehow my Christian name was duplicated with the end result that Peter became Peterer. I tried a new registration however the same email address was flagged and the second registration effort was abandoned. Is it possible to delete all details of my registration?

If you just want to correct your registration details, select the account tab then personal info.

To the right of registration name and address select edit.

Then to the right of registration details select change.

Make changes and save.
