Hi guys, I've just finished building a new plug-in called autosave which is designed to save the progress of forms by saving the fields to cookies so you won't lose anything.
http://rikrikrik.com/jquery/autosave/ I've not fully released it yet as I was hoping for some feedback on what could be changed or added to make it better Hope you like it, Rik -- Rik Lomas http://rikrikrik.com
