How do I set up my computer so that it stops showing my previously asked questions?

I always ask questions on Yahoo! Answers and I am on a shared computer. One of the people whom I share my computer with also goes onto Yahoo! Answers and every time they type in a question in the Ask your question column, they can see what I have previously asked. How do I change this so that my questions don`t save into this computer? Thanks .
