Designing a UI for a forum-type thread

General
1

I need a UI for a forum-type thread where one post can have multiple replies, multiple levels.

Does anyone have any suggestions on the best way to design this? A regular table with indents (just not sure how to add new posts in the right place), a TreeTable, or a layout for each post containing the various labels with indents?

I would definitely not use a Table. CSSLayouts with left margins controlled by code (add style name for how many steps you want to indent) is the way to go, I think.
