To add to what Cåm has said, if you are an admin on a wiki, you can use verbatim tags (see Help:Verbatim tags) to force individual wiki pages to render raw HTML &mdash; bypassing the wikitext parser entirely &mdash; in which case all of those HTML tags (marquee, etc.) will work just fine. This should be used very rarely only in cases of unique pages that really require it.
