• That disclaimer only appears below the form for posting new nodes, not wen posting comments.
• That disclaimer does not appear on the "Preview" page itself ... just the " If something looked unlike you expected it to you might need to check out Writeup Formatting Tips" disclaimer.

Personally, I think having the full version of the disclaimer show up on the "Reply" page, and on the "Preview" age (for both top level nodes, and replies) would reduce a lot of this confusion.
