How does one sign OUT from a public computer?

[marknberk]

Recently I signed IN to my eBay account on a PUBLIC computer, and neglected to un-check the little

box asking if I wanted eBay to keep me signed in. BIG mistake. Every time I come back to this public

terminal and eBay, it says 'Hi, Mark' in the upper left before I've signed in!  HOW DO I GET RID OF THIS?

It says you can remove this in one's My eBay, but for the life of me, I can't find it.  What am I missing?
