[Skunkworks] How to make Yahoo mail stop asking me to enter captcha?

I have this problem in a number of cyber cafes and yahoo mail. It goes further by asking for the secret question a user choose while registering. How can they be stopped? -- Regards, Job Njogu Muriuki, Phone: (+254) - 722906324 | 736333075 Skype: heviejob | Yahoo: heviejob Address: 42665 00100 Nrb
