Several years ago I created this website & now would like to change the theme. Can I do that & still retain the text, home page and additional pages that are there?
as don't see much on the pages you can redesign anyway you want
your pages will still be their all you are changing is your design
Also be aware you only have a free hosted subdomain so if you do decide to put pictures up on the pages make sure optimized and small images as you only have so much space.
but be sure of the design and look you want because way things display can change with template you choose
