Ticketing system (sorta)

[eluser]Bionicjoe[/eluser]
I've built the basics of a system to record tickets, but I'm stuck at the updates portion.

A ticket will need to have updates recorded and then displayed in what is basically a blog-comments fashion. I find tutorials on blogs & comments but they are so simple that they're not functional in the real world.

I need a form at the top of the page that shows the ticket info in editable fields that can be updated with a blank 'UPDATE' field.
Below the form I need each previous update listed in non-editable text, like a blog comment.

The form part I got, but I can't put it together with the UPDATE part.

Any good tutorials on this?
