How do I edit my nickname (middle name)?

We removed this field several years ago. Unfortunately, many people used it for a different purpose than the one it was intended for, such as to promote goods and services, or by putting special symbols in there that complicated the search process. You can put your nickname in About me or Interests here

If you have a middle name set, it will still be displayed. If you want to remove it, you can do so here.

Note that you cannot set a new middle name after removing the old one.
