Looks like a newbie question - Welcome to the group! There could be plenty of scenarios in this case:
Can u login with a valid username-password?
Appropraite error messages displayed if username/password is invalid - or if the user is blocked - expired etc?
Cancel button works?
All links take you to the appropriate pages?
whether the page appears in a stipulated time or not? (more on this topic in the FAQs of the Load and Performance testing forum)
Tab order ok?
Size of objects (text fields, buttons, links etc) are ok?
Appeasing to the eye?
Title is as expected?
Also with the links, check different resolutions to make sure that any link wrapping isn't too confusing and make sure that the link colors don't blend in with the background and I usally try to point out if the background of the page isn't being enforced.
Well thats my two cents worth.... [img]images/icons/smile.gif[/img]
