Start with something really simple: a multi-field registration form that you want to submit with Ajax instead of using the regular Web form Posting path.

We're also looking to increase community participation in the RDK 2 - so if you're using the RDK for something cool, let us know on the Discussions TAB, and submit Patches on the Source Code TAB.

Ajax applications don't have to submit to a server-side program and refresh the page every time something happens, and that means less waiting (at least in theory).
