It came up when I searched "PHP Ajax", and I'd like to know if it's worth my time and effort, or if I should branch out and add in Ajax functionality without a toolkit to help me.
(I'm working on a website for a friend, and I'd like to add a little bit of Ajax to the RSVP page (not yet up) to help the user experience. If it's too much effort, I will do it old-school with lots of post-backs.)
