You certainly have a name. Tell your software about your name, and your software will know it's you who is sitting there, writing a letter.
The benefits of having a name
OpenOffice.org offers multiple benefits for those users who enter their name:
your name will be known by the spell checker, even for Rumpelstiltskin
your name will be inserted as sender in form letters and on envelopes
your name will be inserted as “author” in your Writer documents
When your name is inserted as an author in your text documents, then your text documents will always be opened with the same view where you did save them.
When you saved the document with the cursor on top of page 23, the next time you open the document the cursor will at that position again. When another person with another name opens the same document, the document shows the top of the first page by default.
To enter your name and other personal data
Choose Tools - Options - OpenOffice.org - User data.
To remove your author name from the current document
If you don't want your name to be inserted as the author of the current document, remove the user information:
Choose File - Properties. Click the General tab.
Uncheck “Apply user data” and click Reset. Click OK.
Save the document.
