Below you will find some advice on how to create web forms that are full of usability and accessibility.
Form1. Line up your elements. Do not leave your forms looking jagged.
Form2. Use labels to give your user more to click at. (Click Name or Address).
Form3. Users may not know of the label, so change the cursor to show something will happen. (does not work in FF2.0)
Form4. Use some JavaScript to focus on the first field of a form (see source)
Form5. Lets say if you have some text in a form field to give the user some information. When the user clicks in that field to help them out you can highlight the text making it easier to delete.
