I'm just wondering if there's an easy way to force a defined page to truncate onto additional pages?

Just to explain what I mean, on my new site at www.silkblooms.co.uk I've created a testimonials page where our new brides can upload and submit photos and text about their wedding:

http://www.silkblooms.co.uk/index.ph...stomer_gallery

Every time I get a new testimonial, I just add it to the top of the page via html in the define pages editor. Obviously, I can't keep adding to this page as it'll end up too long. So, my question is how to make the page length limit itself and force the additional content onto a new page?

Is this easy to do or would I be better just manually creating additional defined pages each time and adding <page 2> and <page 3> links to the bottom manually?
