This remembers me the Theory7 and old Ego7 contact forum 
The AS2 contact form has field validation on every field except herd about. The form height auto adjusts to the height of the msg textfield. I have validation on all fields except herd about. The form also on completion will send a courtesy note to the user who submitted them form. This can be turned off in the php script.
Both fla and php script are fully comment. Please check out my other files.
