External Links in Sharepoint

I have been asked to put some links to careers websites on the Intranet (we use moss 2007)
The sites need login details just wondering if i can use a webpart to do this so the children dont have to type it in each time.

sites are www.kudosonline.co.uk and Careerscape Online log in

There isn't a web part that will do auto txt for you - have a look at how the careers website works and the URL may allow you to put in a username and password.
