PeopleSoft is a company that makes web applications used a lot in industry, government, and education, etc... My university uses it for enrollment purposes, financial purposes, etc... You can add or drop courses with it, view your transcript, view your financial record with the university, etc... Handy little thing, if they'd support it better. The damn thing is down half the time. Then again, this is the first 4 months it's been active, so I'm trusting they're just getting the kinks worked out.

And as far as PeopleSoft goes, it works beautifully on the latest Mozilla for me.
