I recently did this for a client of mine. I intend to write the process up on a blog post (eventually) but for you – here are the steps involved.
1. Create a template in your theme for your about pages
2. Create about pages, assign template created in step 1 to each page
3. Create custom field ‘author’ on about pages and assign the numerical author id
Here’s the code for your template. It should be place outside the loop (ie. before or after the main template loop):
Recent blog posts
< ?php $numposts = 3; // number of posts to show if ($author = get_post_meta($post->ID, ‘author’, true)) :
if (have_posts()) : while (have_posts()) : the_post(); ?>
