It's for a message board, where I've implemented Rich HTML posting
(contentEditable). It works fine except for when someone copy-and-
pastes from a site that uses DIV tags for layout. In those cases, if
the poster doesn't grab the entire page, then it's not uncommon for
the opening or closing DIV tags to be missing.
I've been rebuilding this section using DIV instead of tables, but
those missing tags in the posts cause major layout errors. I can
correct it by surrounding posts with a table, but I figure that a
better long-term solution would be to correct the missing tags as soon
as they're posted.
