Hi,

I want to create a twitter like user registration form for php web application. 

I have searched alot but couldn't find any all in one JQuery Plugin which provide the following functionalities to my webform-

1. Form Feild highlight when onFocus and on error

2. Proper client-side form validation

4. Check user name availability

5. Check email availability

Can anyone know any all in one plug-in which I can add to php registration forms to make my forms live?

I'm extremely new to jquery and it my first ever jquery project.

So, any help will be really appreciated!
