Put a link back to the home page somewhere in each of your pages. Don't use a font, BR or P to format a heading. The browser will format it for you. If you have a translation of a page in another language, put icons or links to it right under the header. People are used to seeing these link colors when they navigate all web sites.
Many people find light text on a dark background very difficult to read.
Use external style sheets for styles so the user can use their own preferences. Your sentences, paragraphs, headers, titles, list items should use punctuation consistently. Reconsider animated GIFs - many people find moving images annoying. If you MUST use the PRE tag, create short lines so that browsers will be able to read the text without scrolling sideways even on VGA screens. Use links, don't talk about them.
