Privacy: How to clear previous SKYPE login attempts?

How do we clear the long list of previous Skype login attempts?

In Skype 3.0.0.198 on Windows XP, when I start Skype, it comes up with a "Skype Name" field that has dozens of old prior login attempts.

I don't want other people seeing those login attempts. How do I clear the loooong "Skype Name" list on Windows XP?

Unfortunately, the CCleaner 1.36.430 freeware system optimization and privacy tool does NOT clean old Skype Names. Neither does MRU Blaster 1.5 (March 30, 2004) clean out the long list of Skype Names.

I didn't find how to clear the Skype Name list in the Skype FAQ:

So, I ask you for help. Where is the Skype Name list stored and how do I clear it out?
