is there a code where i can delete the "expertise, occupation..ect." off my profile on xanga without deleting my profile picture?

Simple just don't put anything there and nothing will show up.

go to http://www.xanga.com/Private/profilebasic.aspx and on the right, make sure it is checked as 'hide' for all the things you don't want to show up.

This is a just incase she doesn't find it.
Expertise 2nd box.
Occupation / industry are at the bottom.

And just do what Spiritedfreak said.
