I'd like to suggest a very simple idea for SLASH: forced
post previewing. All we need is a checkbox added to a
user's options page for 'forced post previewing'. If this
was checked, it would remove the 'Submit' button from
the initial post submit form (for a reply comment), but
leave it on the preview page. Obviously, this would have
the effect of requiring at least one preview before
posting, much like is required for submitting a story. I
think this would be a very useful feature that I, amongst
many other users, would like, and it would improve the
quality of many posts too. Fewer typos!
