Hi Marius,
Thanks for the great replys, I'll just focus on one area.
About the validation error messages, I mean more specifically can I
have the error messages for each <input on the form.
For example if someone types a phone number incorrect, but perhaps I
have 10 fields in my form, I want the phone number to have a error
message next to it. Also they got the post code wrong, so I need a
error message next to it as well.
As I understand it, all error messages are lumped together into the
one div and shown.

Please see notices/error/warnings. For instance S.error("msgid", "an
error") and int your page you can put:
<lift:msg id="msgid" errorClass="error_class"
warningClass="warning_class"/> anywhere ... probably near by your
form field.
Thanks, Philip
