The problem is that to contact a site to see what its load is like is just about the same as contacting it to get a packet. That's because most of what they are saying is bullshit. There seems to be no standard for searching through forms. There is, but it's easy to defeat with careless form construction. Tabs work right normally.
Forms are clunky.
They can be prettied up, but it's not worth the effort. Good use of them, however, can be attractive. Generally, folks making forms, however, don't have incentive to make the form nicer. The reason for this is that they already have sold you by the time you are filling out the form. You have X windows.
